2017 journal article

Subject-variability effects on micron particle deposition in human nasal cavities

JOURNAL OF AEROSOL SCIENCE, 115, 12–28.

By: H. Calmet *, C. Kleinstreuer n, G. Houzeaux *, A. Kolanjiyil n, O. Lehmkuhl *, E. Olivares *, M. Vazquez *

author keywords: Nasal cavities; Particle transport/deposition; Computational fluid-particle dynamics
TL;DR: Computer simulations of the airflow and particle dynamics in human nasal cavities are important for local, segmental and total deposition predictions of both inhaled toxic and therapeutic particles, and a new dimensionless group with which total particle deposition efficiency curves are very similar for all airway models is developed.

2016 journal article

Computationally efficient analysis of particle transport and deposition in a human whole-lung-airway model. Part I: Theory and model validation

COMPUTERS IN BIOLOGY AND MEDICINE, 79, 193–204.

By: A. Kolanjiyil n & C. Kleinstreuer n

author keywords: Lung; Airflow; Whole lung airway modeling; Computational fluid dynamics; Particle deposition
MeSH headings : Computational Biology; Computer Simulation; Humans; Hydrodynamics; Lung / physiology; Models, Biological; Respiratory Mechanics / physiology; Respiratory Transport / physiology; Trachea / physiology
TL;DR: The present new whole-lung-airway model (WLAM) represents the actual lung geometry via a basic 3-D mouth-to-trachea configuration while all subsequent airways are lumped together, i.e., reduced to an exponentially expanding 1-D conduit. (via Semantic Scholar)

2016 journal article

Laminar/turbulent airflow and microsphere deposition in a patient-specific airway geometry using an open-source solver

INTERNATIONAL JOURNAL OF BIOMEDICAL ENGINEERING AND TECHNOLOGY, 22(2), 145–161.

By: M. Vaish n, C. Kleinstreuer n, A. Kolanjiyil n, N. Saini n & N. Pillalamarri*

author keywords: OpenFOAM solver; patient-specific geometry and idealised configuration; modified eddy interaction model; microsphere transport and deposition; practical Stokes number range
TL;DR: Using the open-source software OpenFOAM as the solver, airflow and microsphere transport have been simulated in a patient-specific lung-airway model and results indicate that selection of an appropriate near-wall correction factor can reduce the problem of subject variability for different lung- airway configurations.
