A Compression-Directional Entropic Stress Method for Shock-Regularized Compressible Flow
Bonan Xu, Chihyung Wen, Peixu Guo
We introduce the Compression-Directional Entropic Stress (CoDeS) method inspired by information geometric regularization. CoDeS replaces scalar multidimensional entropic pressure w…

A Central Differential Flux with High-Order Dissipation for Robust Simulations of Transcritical Flows
Bonan Xu, Chang Sun, Peixu Guo
The simulation of transcritical flows remains challenging due to strong thermodynamic nonlinearities that induce spurious pressure oscillations in conventional schemes.While primit…
