A hyperbolic relaxation system of the incompressible Navier-Stokes equations with artificial compressibility
Qian Huang, Christian Rohde, Wen-An Yong +1
We introduce a new hyperbolic approximation to the incompressible Navier-Stokes equations by incorporating a first-order relaxation and using the artificial compressibility method.…

Stability analysis of an extended quadrature method of moments for kinetic equations
Ruixi Zhang, Qian Huang, Wen-An Yong
This paper performs a stability analysis of a class of moment closure systems derived with an extended quadrature method of moments (EQMOM) for the one-dimensional BGK equation. Th…
