Adjoint shape optimization from the continuum to free-molecular gas flows
Ruifeng Yuan, Lei Wu
An adjoint-based shape optimization method for solid bodies subjected to both rarefied and continuum gas flows is proposed. The gas-kinetic BGK equation with the diffuse-reflection…

Capturing the influence of intermolecular potential in rarefied gas flows by a kinetic model with velocity-dependent collision frequency
Yuan RuiFeng, Wu Lei
A kinetic model called the -model is proposed to replace the complicated Boltzmann collision operator in the simulation of rarefied flows of monatomic gas. The model follows the…
