Abstract: 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.

Key words: domain decomposition method, Euler equation, patched grid
