A novel Cercignani-Lampis boundary model for discrete velocity methods in predicting rarefied and multi-scale flows
Jianfeng Chen, Sha Liu, Rui Zhang +5
To extend the discrete velocity method (DVM) and unified methods to more realistic boundary conditions, a Cercignani-Lampis (CL) boundary with different momentum and thermal energy…

Hypersonic wave wall flow based on gas kinetic method
Yining Yang, Rui Zhang, Jianfeng Chen +4
The transition of hypersonic boundary layer can lead to a several-fold increase in surface heat flux and skin friction for the aircraft, significantly impacting its flight performa…
