Journal ArticleDOI
A unified gas-kinetic scheme for continuum and rarefied flows IV
TL;DR: The UGKS as discussed by the authors is a direct modeling method in the mesh size scale, and its underlying flow physics depends on the resolution of the cell size relative to the particle mean free path.
Journal ArticleDOI
Gas flows in microchannels and microtubes
TL;DR: In this paper, the authors analyzed compressible gas flows through microchannels or microtubes, and developed two complete sets of asymptotic solutions to obtain proper estimations for the Reynolds and Mach numbers at the outlets.
Proceedings ArticleDOI
A Hybrid Continuum / Particle Approach for Micro‐Scale Gas Flows
TL;DR: In this article, a hybrid continuum/particle approach is proposed for micro scale gas flows in which the particle cells are used as ghost cells to preserve the hydrodynamic information that the continuum solver uses.
Journal ArticleDOI
Improved sampling techniques for the direct simulation Monte Carlo method
TL;DR: Two techniques to speedup related sampling processes are presented, very efficient for sampling geometric locations of new particles and the other is useful for the Larsen-Borgnakke energy distribution.
Journal ArticleDOI
Numerical study of chemically reacting flow in a shock tube using a high-order point-implicit scheme
TL;DR: In this article, a high-resolution weighted essentially non-oscillatory (WENO) solver was employed to capture the complex shock structures, together with a point-implicit method to overcome the stiffness of the chemical production term in the multicomponent Navier-Stokes equations.
