摘要
研究等熵流Chaplygin气体的初值为2个常状态的二维黎曼问题.使用平面波法和特征分析方法,在适当的广义Rankine-Hugoniot条件和熵条件下,构造出该黎曼问题的5类平面波解,这些解由后向(前向)疏散波、后向(前向)激波、接触间断以及δ-激波构成.
The two-dimensional Riemann problem with initial data of two constant states for isentropic Chaplygin gas dynamic system is studied in the paper.Using plane wave and characteristic analysis methods,under the suitable generalized Rankine-Hugoniot relation and entropy condition,five kinds of plane wave solutions to the Riemann problem are constructed,which are composed of back（forward） rarefaction wave,back（forward） shock wave,contact discontinuity and δ-shock wave.
