A simplified unified wave-particle method for diatomic gases with rotational and vibrational non-equilibrium
Sirui Yang, Chengwen Zhong, Ningchao Ding +4
The hypersonic flow around near-space vehicles constitutes a multi-scale flow problem. Due to insufficient molecular collisions to achieve equilibrium, rarefied gas effects are pre…

Efficient mesh deformation using radial basis functions with a grouping-circular-based greedy algorithm
Hong Fang, He Zhang, Fanli Shan +3
A grouping-circular-based (GCB) greedy algorithm is proposed to promote the efficiency of mesh deformation. By incorporating the multigrid concept that the computational errors on…
