一种计算激波的守恒差分格式

A CONSERVATIVE DIFFERENCE SCHEME FOR SHOCK CALCULATION

介绍了一种处理激波间断解的差分格式，此格式是基于在间断解的两侧使用不同计算公式的守恒差分格式；证明了该格式满足离散熵条件．

Ａ treatment to sharpen discontinuities for shock tracking methods is introduced .The treatment is a modification of the scheme that makes the computation on each side of the discontinuity only using the information from that side and eliminates the conservation errors. It is proven that our conservation difference scheme satisfies the dispersed entropy condition under some conditions.
