An efficient treatment of heat-flux boundary conditions in GSIS for rarefied gas flows
Yanbing Zhang, Ruifeng Yuan, Liyan Luo +1
Heat-flux boundary conditions are challenging to implement efficiently in rarefied gas flow simulations because the wall-reflected gas temperature and density must be determined dy…
A fast-converging and asymptotic-preserving method for adjoint shape optimization of rarefied gas flows
Yanbing Zhang, Ruifeng Yuan, Lei Wu
Adjoint based shape optimization is a powerful technique in fluid-dynamics optimization, capable of identifying an optimal shape within only dozens of design iterations. However, w…
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…
