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…
Self-supervised learning based on Transformer for flow reconstruction and prediction
Bonan Xu, Yuanye Zhou, Xin Bian
Machine learning has great potential for efficient reconstruction and prediction of flow fields. However, existing datasets may have highly diversified labels for different flow sc…
An adaptive primitive-conservative scheme for high speed transcritical flow with an arbitrary equation of state
Bonan Xu, Hanhui Jin, Yu Guo +1
When fully conservative methods are used to simulate transcritical flow, spurious pressure oscillations and numerical instability are generated. The strength and speed of propagati…
Transcritical transition of the fluid around the interface
Bonan Xu, Yanqi Zhu, Hanhui Jin +2
In this letter, we provide fundamental insights into the dynamic transcritical transition process using molecular dynamics simulations. A transcritical region, which covers three d…
