Adaptive GSIS for rarefied gas flow simulations
Yanbing Zhang, Jianan Zeng, Lei Wu
The parallel solver of the general synthetic iterative scheme (GSIS), as recently developed by Zhang \textit{et. al.} in Comput. Fluids 281 (2024) 106374, is an efficient method to…

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…

General synthetic iterative scheme for rarefied gas mixture flows
Jianan Zeng, Qi Li, Lei Wu
The numerical simulation of rarefied gas mixtures with disparate mass and concentration is a huge research challenge. Based on our recent kinetic modelling for monatomic gas mixtur…
