We extend a hybrid DSMC/Navier–Stokes (NS) approach to unify the DSMC and the NS simulators in one framework capable of solving the mixed non-equilibrium and near-equilibrium flow regions efficiently. Furthermore, we use a one-way state-based coupling (Dirichlet–Dirichlet boundary-condition ...
time-dependent Poiseuille flowglobal existenceThe time-dependent Navier–Stokes system is studied in a two-dimensional domain with strip-like outlets to infinity in weighted Sobolev function spaces. It is proved that under natural compatibility conditions there exists a unique solution with prescribed ...
flow past cylinderThis paper presents a numerical algorithm using the pseudostress–velocity formulation to solve incompressible Newtonian flows. The pseudostress–velocity formulation is a variation of the stress–velocity formulation, which does not require symmetric tensor spaces in the finite element ...

The effect of temperature-dependent specific heats becomes particularly important when there are significant variations in temperature in the flow field, such as gas flows containing strong shock waves. For this reason, herein, we attempt to extend the two-temperature NS equations to a gas with ...
