A three-dimensional mixed modal discontinuous Galerkin (DG) method based on tetrahedral
meshes was developed for simulating all flow regimes from subsonic to hypersonic rarefied …

The present study reports the numerical analyses of lateral jet interaction around a Terminal
High Altitude Area Defense-type (THAAD-type) model in hypersonic rarefied flows, with the …

Abstract In shock-induced Richtmyer–Meshkov instability, the polygonal bubbles, including
the rectangular interface can offer favorable circumstances for shock refraction research …

Abstract The Richtmyer–Meshkov instability of a shock-driven SF 6 square bubble in
monatomic, diatomic, and polyatomic gases is investigated numerically. The focus was …

We investigate the flow physics of non-equilibrium gases in interaction with solid particles in
a microscale shock tube and the collection efficiency in the jet impingement on a permeable …

The nccrFOAM suite is a collection of nonlinear coupled constitutive relation (NCCR) solvers
for rarefied and microscale gas flows with vibrational non-equilibrium, in conjunction with the …

A high-fidelity computational framework for predicting the interaction of a rocket plume with a
dust blanket in an almost vacuum ambient that represents the descent/ascend phase of …

Permeability of fibrous porous structures is a key material property for predicting the gas flow
path during working conditions. A direct simulation Monte Carlo method is proposed to study …

The aerothermodynamics of re-entry vehicles vary significantly upon re-entry, descent, and
landing, because of the drastic changes in atmospheric density and velocity. In highly …

We develop an axisymmetric lattice Boltzmann (LB) model to simulate microcylindrical
Couette gas flows (MCGF) in the slip regime and transition regime, respectively. A kinetic …
