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…
Multiscale simulation of rarefied gas flows in Divertor Tokamak Test facility
Wei Li, Yanbing Zhang, Jianan Zeng +1
Simulating gas flow within the divertor, which is a crucial component in nuclear fusion reactors, is essential for assessing and enhancing its design and performance. Traditional m…
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…
