The traditional bottom-up technology to process these short staple fibers is spinning. State-of-the-art spinning technology requires not only high throughput processing of the cellulose fibers, but also the addition of functionalities and value into the supply chain. Recently, a modified ring spinning system has been developed which introduces a false twist into a traditional ring spinning frame. The modified system produces cellulose yarns that have a high strength but low twist, and a soft hand similar to cashmere. Unlike traditional textile finishing treatments which consume plenty of chemicals, water, and energy, this method is purely physical and sustainable. The superior properties of the modified cellulose yarns are attributed to the modified yarn morphology and structure. Theoretical investigation is, therefore, important in understanding of the spinning mechanisms of the modified ring spinning process that changes the morphology and structure of the cellulose yarns. In this paper, yarn behavior constrained to lie on a moving solid cylinder was theoretically and experimentally investigated. Equations of motion were derived based on the Cosserat theory and numerical solutions in steady-state were obtained in terms of yarn spatial path, yarn tension, twist distribution, yarn bending, and torsional moments. Effects of various spinning parameters including wrap angle, speed of the moving cylinder, yarn diameter, yarn tension, yarn twist, and frictional coefficient, on yarn behavior were discussed. The results suggested that in most cases the bending and torsional moments are of the same order of magnitude, and thus the effect of bending cannot be neglected. Experiments in the modified ring spinning system were conducted to verify the theoretical work, and good agreement has been made. Some simulation results of this study were compared with the results of earlier models as well as with experimental data, and it was found that the current model can obtain a more accurate prediction than previous models in terms of yarn twist and tension. The results gained from this study will enrich our understanding of the spinning mechanism of the modified ring spinning process and better handle of cellulose fibers for functional and value-added applications.}, number={16}, journal={Cellulose}, publisher={Springer Science and Business Media LLC}, author={Yin, Rong and Tao, Xiaoming and Jasper, Warren}, year={2020}, month={Sep}, pages={9683–9698} }

Omission of the Laplace pressure results in overestimating the line tension by several orders of magnitude and contributes to significant errors in predicting the contact angle for droplet volumes ranging from micro-liters to atto-liters. This paper addresses this issue and offers a correct inclusion of VdP as a virtual work term in the free energy variation at the liquid-vapor boundary for both flat and curved surfaces. While the Laplace pressure is constant at the liquid-vapor interface as a condition of equilibrium, the variation of the Laplace pressure is not zero, as it influences both the shape (spherical cap) and contact angle of sessile droplets. Inclusion of this term leads naturally to a definition of the line tension as a volume dependent term, and more importantly to a correct prediction in both sign and magnitude of the line tension value. The inclusion of VdP work predicts a cubic relationship between the cosine of the contact angle and droplet line radius. This new model extends existing theories on the behavior of nanosized droplets and its predictions exhibit quantitative agreement with experimental results for nonane, dodecane, fullerene, and glycerol trioleate over a range of 15 orders of magnitude in droplet volume. Finally, we also theorize the existence of two different equilibrium contact angles at lower droplet volumes. These two values diverge with the inverse line radius.}, journal={JOURNAL OF MOLECULAR LIQUIDS}, author={Jasper, Warren J. and Anand, Nadish}, year={2019}, month={May}, pages={196–203} }

In such filters, the filtration of submicron aerosol particles occurs as air passes through millions of microchannels. This article investigates the flow and filtration mechanisms in a representative rectangular microchannel of an electret monolith filter. An improved incompressible lattice Boltzmann method with Bhatnagar–Gross–Krook (traditionally shortened as LBGK) and lattice velocity D3Q15 model is employed to simulate no-slip and slip flows in the rectangular microchannels of a monolith filter. We considered mono-disperse submicron particles and one-way coupling (particle motion was affected by the flow, but the presence of particles did not affect the flow). Based on flow computations, the effects of key dimensionless parameters (Reynolds number, Knudsen number, Stokes number and the dimensionless length of the channel) on the total capture efficiency of mono-disperse submicron particles were investigated. Our results indicate that the optimal monolith filter should be characterized by a Knudsen number between 0.022 and 0.044, and that the dimensionless length of the channel should be between 4 and 8.

Three different configurations, one with eight 1 cm fans (8 × 1 model); one with four 2 cm fans (4 × 2 model); and one with four 1 cm fans (4 × 1 model) were studied at different inlet air velocities of 0.25 m/s, 0.5 m/s, 0.75 m/s and 1.0 m/s and with air gaps of 3 mm, 7 mm and 11 mm. The simulations showed that the convective and evaporative heat transfer coefficients varied with a power function of inlet air velocity, but the exponent was larger than reported in the literature. At lower air velocities, the heat transfer coefficients increased as the gap between the skin and the undergarment widened. At higher inlet air velocities, 3 mm and 11 mm air gaps showed the highest heat transfer values. The ratios of the heat transfer coefficients of the 8 × 1 and 4 × 2 models to the 4 × 1 models were both less than 2 indicating that doubling the inlet airflow does not double the heat transfer capability. The ratios of convective to evaporative heat transfer coefficients were around 8.63 K/kPa (SD 0.25 K/kPa), and were independent on the air velocity and configurations of the cooling system, suggesting that convective and evaporative heat transfer are fully coupled. This ratio also shows that the vapor permeability index of our system is around 0.52.

The aim of this system was to reduce the overall energy consumption and realize energy savings by minimizing air-conditioning during the summer months without compromising human comfort. The proposed system consists of a series of microfans, placed in a ribbon and attached to a garment to provide cooling through convective and evaporative heat transfer. Three different configurations were analyzed: one had four 1 cm microfans; the second one had four 2 cm fans and the third had eight 1 cm fans. With these configurations, a series of 2-dimensional models of the convective and evaporative heat transfer at the skin surface were numerically simulated using COMSOL Multiphysics at 0.25 m/s, 0.5 m/s, 0.75 m/s and 1 m/s inlet airflow velocities. The convective and evaporative heat transfer coefficients at the skin surface were calculated which indicated peaks at the skin surface facing the inlet airflows from the fans. The combination of two opposing sub-flows produced small eddies and increased the coefficient of convective and evaporative heat transfer at high inlet airflow velocities and thicker air gaps. Our convective cooling system significantly improved the convective and evaporative heat transfer coefficients when the inlet airflows were at 0.75 m/s and 1 m/s.

A Lagranian continuous random walk (CRW) model is developed to simulate soot particulate motion, which considers a succession of uncorrelated random forcing and drift corrections. The effects of particle inertia, turbulent fluctuation, and lift on the particle motion and trajectory are analyzed. Correlations of the uniformity index of the exhaust gas and soot particles with the flow rate, soot loading, and inlet expansion angle are evaluated. The results show that there is a two-peak phenomenon in the soot distribution at the front entrance of the filter, which is comprised of a peak in the central area due to inertia and a second peak in the periphery owing to diffusion and recirculation action.

Violation of one or more of these assumptions will lead to errors in predicting the concentrations of dyes in a dyebath and subsequent exhaustion calculations.}, number={3}, journal={COLORATION TECHNOLOGY}, publisher={Wiley}, author={Guenay, Melih and Jasper, Warren J.}, year={2010}, pages={140–146} }

Modeling and simulations of the particle trajectories are carried out to evaluate the probability of capture by the filter’s front surface and filter channel’s inner wall. Due to Brownian motion and electrostatic attraction, the particles exhibit a random walk and their trajectories deviate from the streamlines of the fluid flow. Particle trajectories are computed by the integration of Newton’s second law, where the electrostatic force, the Brownian motion force resulting from random collisions of the particle with air molecules, and the drag force from the surrounding fluid are all taken into account. A computer simulation for computing the particle trajectories and evaluating the probability of particle capture by the filter was developed. For this model, both flow field and electric field must be provided. The electric charge was assumed to be uniformly distributed along the edge of the channels of the filter and calculated numerically. The flow field is difficult to obtain due to the complex geometry of the model. The commercial CFD package ANSYS CFX [1] is used to compute the flow field. The resulting velocity flow field is then used to evaluate the drag force on the particles. We assume a one-way coupling between the fluid flow and the particle motion. Although there can be over one million uniformly distributed channels per square centimeter in the monolith filter, for simulation purposes, a single unit cell which models only one channel is used. The single unit model effectively describes the behavior of particles outside and inside the channels of monolith filter. The effects of different forces and different particle sizes were analyzed to investigate which factors affect the capture efficiency.}, journal={2010 14th International Heat Transfer Conference, Volume 6}, publisher={ASMEDC}, author={Wu, M. and Kuznetsov, A.

Unlike traditional fibrous filters which comprise external flow around a fiber, monolith filters are modeled as internal flow through small channels. Analogous to single fiber theory for external flows, single channel theory is used to analyze basic fluid mechanics in monolith filters and predict filtration efficiencies. The model incorporates three forces: hydrodynamic forces, electrostatic forces, and Brownian motion. Fluid velocity within the channels is calculated by using an analytical solution for circular channel flow, within which the slip boundary condition is considered because of small length scales. This velocity field is then used to evaluate the drag force on the particle according to Stokes’s law. For this model, a one-way coupling between the fluid flow and the particle motion is assumed due to the fact that the relaxation time for the particles simulated in this paper is very small compared to the time the particles spend in the channel. The electrostatic field is computed assuming a uniform charge distribution on the inner surface of a cylindrical channel of finite length. Using a Monte Carlo simulation, particles are randomly injected into a single channel to determine the filtration efficiency.}, number={4}, journal={PHYSICS OF FLUIDS}, publisher={AIP Publishing}, author={Wu, Mengbai and Kuznetsov, Andrey V. and Jasper, Warren J.}, year={2010}, month={Apr} }

Electret media, exposed to isopropanol (IPA) in the liquid phase, exhibited reduced filtration efficiency with negligible changes in the pressure drop across the media.

Solvent-induced efficiency deterioration of electret filter media was hypothesized to originate from charge deterioration rather than charge masking. The charge of the individual fibers in filter media was characterized using electrostatic force microscopy (EFM). EFM investigation produced evidence that exposure to IPA in the liquid phase affected the electrostatic charges on fibers.

The filtration performance for all three types of electret filter media decreased over 30% when the samples were exposed to liquid xylene. Pressure drop changes of the filter media prior and after exposure to liquid xylene were statistically negligible.

Parametric control methods require some a priori knowledge of the process model structure as well as possibly the range of the process model parameters. Such methods as nonlinear robust control and adaptive control belong to this category. In the case when model identification is not feasible, nonparametric methods offer an alternative solution to control. One such method, fuzzy logic control (FLC) is used to simulate the decision-making activities of an experienced expert. Usually, the control decisions of an expert can be expressed linguistically as a set of heuristic decision rules. These rules are used to build rulebases for FLC; further algorithms are used to convert the results of these rules to quantitative outputs. Several fuzzy logic control schemes have been developed, including some adaptive methods. However, many of these methods can only handle single input, single output (SISO) systems. In this paper, a multi-input, multi-output scheme is developed. The method is based upon a SISO technique previously developed for a self-learning FLC with on-line scaling factor tuning. The method employs optimization techniques to provide the FLC outputs and an application to dyeing processes is discussed. Simulation results employing the MIMO FLC on a three dyeing process are presented. Finally the experimental dyeing process testbed which will be used for hardware verification is discussed.}, journal={Proceedings of 1994 American Control Conference - ACC '94}, publisher={IEEE}, author={Lu, Jun and Jasper, W. and Lee, G.K.}, year={2005}, month={Aug} }

Model-based control methods generally require some knowledge of system structure and possibly some bounds on the uncertainty of the system parameters. Such methods as robust control and adaptive control belong to this category. In a case where system identification is not feasible, knowledge-based methods offer an alternative solution to control. One such method, fuzzy logic control (FLC), may be used to simulate the decision making process of an experienced expert. Usually, the control decisions of an expert can be expressed linguistically as a set of heuristic decision rules. The rules are used to build rulebases for FLC; further, algorithms are used to convert the results of the rules to quantitative outputs.This article presents an adaptive multi-input, multi-output (MIMO) fuzzy logic control method whi...}, number={3}, journal={Intelligent Automation & Soft Computing}, publisher={Computers, Materials and Continua (Tech Science Press)}, author={Lu, Jun and Lee, Gordon and Jasper, Warren}, year={1995}, month={Jan}, pages={259–278} }

The wavelet transform, used as a multi-resolution spectral filter, is able to give both spectral and frequency information about a fabric. For the samples tested, the wavelet transform can characterize defects due to missing picks and ends faster and more accurately than the other methods. }, number={11}, journal={TEXTILE RESEARCH JOURNAL}, publisher={SAGE Publications}, author={JASPER, WJ and POTLAPALLI, H}, year={1995}, month={Nov}, pages={683–692} }
