DOMAIN DECOMPOSITION COMPUTATION ON THE IRREGULAR PATCHED GRIDS
Li Jin, Chen Zemin, Zhu Ziqiang, Li Zhongze
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1998, 15 (6): 726-734.  
Abstract306)      PDF (388KB)(1077)      
An internal coupling condition which can guarantee the conservation of flux on the irregular patched grids for the domain decomposition method is given. The Euler equations are solved by using the finite Volume method combined with van Leer's flux vector splitting. The TVD character and second order accuracy are realized by adopting a new limiter function. Numerical examples are presented as well.

New Limiters Applied to Flux Vector Splitting Schemes
Li Jin, Chen Zemin, Zhu Ziqiang
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1997, 14 (3): 297-304.  
Abstract220)      PDF (311KB)(975)      
A new class of limiter functions is co nstructed which can guarantee the TVD property while maintain the smoothness of the Van.Albada's limiter.When coo rperated with the Flux vector splitting scheme, it gives a stable result for the 3-D viscous flow around a blunt body.
