Flow past a sphere using kinetic theory
by Ying Yap
Abstract: Gas flows generated by nanoscale devices have received significant recent attention. Modeling these flows often requires the use of kinetic theory, because such operation invalidates the use of standard continuum treatments, i.e the Navier-Stokes equations. The Bhatnagar-Gross-Krook (BGK) kinetic model approximates the effect of molecular collisions as a relaxation process, and is often used to describe non-equilibrium gas flows. In this talk, I will present a study of the general 3D flow past a convex body using the BGK model applied to the case of a sphere.
