MSAT: Matrix stability analysis tool for shock-capturing schemes
Weijie Ren, Wenjia Xie, Ye Zhang +2
The simulation of supersonic or hypersonic flows often suffers from numerical shock instabilities if the flow field contains strong shocks, limiting the further application of shoc…

A unified construction of all-speed HLL-type schemes for hypersonic heating computations
Wenjia Xie, Zhengyu Tian, Ye Zhang +1
In this paper, a unified framework to develop all-speed HLL-type schemes for hypersonic heating computations is constructed. Such a unified construction method combines two effecti…
