In addition, the interesting hollow structure of these nanotubes opens new applications such as nanoreactors.}, number={4}, journal={JOURNAL OF THE AMERICAN CHEMICAL SOCIETY}, author={Peng, Huisheng and Jain, Menka and Li, Qingwen and Peterson, Dean E. and Zhu, Yuntian and Jia, Quanxi}, year={2008}, month={Jan}, pages={1130-+} } @article{zhu_kuznetsov_sandeep_2007, title={Mathematical modeling of continuous flow microwave heating of liquids (effects of dielectric properties and design parameters)}, volume={46}, ISSN={["1778-4166"]}, DOI={10.1016/j.ijthermalsci.2006.06.005}, abstractNote={A detailed numerical model is presented to study heat transfer in liquids as they flow continuously in a circular duct that is subjected to microwave heating. Three types of food liquids are investigated: apple sauce, skim milk, and tomato sauce. The transient Maxwell's equations are solved by the finite difference time domain (FDTD) method to describe the electromagnetic field in the microwave cavity and the waveguide. The temperature field inside the applicator duct is determined by the solution of the momentum, energy, and Maxwell's equations. Simulations aid in understanding the effects of dielectric properties of the fluid, the applicator diameter and its location, as well as the geometry of the microwave cavity on the heating process. Numerical results show that the heating pattern strongly depends on the dielectric properties of the fluid in the duct and the geometry of the microwave heating system.}, number={4}, journal={INTERNATIONAL JOURNAL OF THERMAL SCIENCES}, author={Zhu, J. and Kuznetsov, A.

The three-dimensional transient fluid flow as well as electromagnetic and temperature fields are described by a model that includes coupled Maxwell's, continuity, Navier-Stokes, and energy equations. The electromagnetic power and temperature distributions in both the liquid and the particle are taken into account. The hydrodynamic interaction between the solid particle and the carrier fluid is simulated by the force-coupling method (FCM). This article explores the effects of dielectric properties and the inlet position of the particle on microwave energy and temperature distributions inside the particle. The effect of the particle on power absorption in the carrier liquid is studied as well. The results show that electromagnetic power absorption by the particle is greatly influenced by the ratio of dielectric properties of the particle and the liquid as well as the distance between the particle and the location in the applicator where the electromagnetic power takes on its maximum value.}, number={5}, journal={NUMERICAL HEAT TRANSFER PART A-APPLICATIONS}, author={Zhu, J. and Kuznetsov, A.

The modeling is based on the assumption that the flow in the clear fluid region is turbulent while in the porous region the flow remains laminar. The turbulent and laminar flow solutions are matched at the porous/fluid interface, which is assumed rough. Two different models are utilized for calculating turbulent viscosity in the clear fluid region, the algebraic Cebeci–Smith model and a k–ε model. Numerical results obtained utilizing both models are compared and analyzed in detail.}, number={1-2}, journal={INTERNATIONAL COMMUNICATIONS IN HEAT AND MASS TRANSFER}, author={Zhu, J and Kuznetsov, AV}, year={2005}, month={Jan}, pages={10–18} }
