The role of velocity derivative skewness in understanding non-equilibrium turbulence被引量:1
《Chinese Physics B》2020年第11期99-105,共7页Feng Liu Le Fang Liang Shao 
Project supported by the National Natural Science Foundation of China(Grant No.11772032);the Science Foundation of North University of China(Grant No.11026829).
The turbulence governed by the Navier-Stokes equation is paramount in many physical processes.However,it has been considered as a challenging problem due to its inherent nonlinearity,non-equilibrium,and complexity.Her...

An improved global-direction stencil based on the face-area-weighted centroid for the gradient reconstruction of unstructured finite volume methods被引量:2
《Chinese Physics B》2020年第10期109-130,共22页Ling-Fa Kong Yi-Dao Dong Wei Liu Huai-Bao Zhang 
Project supported by the National Key Project, China (Grant No. GJXM92579).
The accuracy of unstructured finite volume methods is greatly influenced by the gradient reconstruction, for which the stencil selection plays a critical role. Compared with the commonly used face-neighbor and vertex-...
