| Abstract: | In this article, the adiabatic chaplygin gas dynamics system is concerned. By using a characteristic method, we obtain all existed elementary waves. And then the solution to the related Riemann problem is constructed which is composed of forward rarefaction wave(shock wave),backward rarefaction wave(shock wave), contact discontinuity and δ wave. |
| Keywords: | Chaplygin gas in adiabatic flow Riemann problem rarefaction wave shock wave contact discontinuity δwave |
