First the thermodynamic characteristics of the van der Waals gas are briefly discussed and then the Rankine-Hugoniot relations are obtained by using the Rayleigh line and the shock adiabatic. It was proved that both the compression and the expansion shocks can exist in the gas whose conditions are close to those at the critical point on the saturation curve. Although this fact has already been well known, several interesting shock characteristics were newly found. Next a Total Variation Diminishing (TVD)-scheme is applied to solve numerically the corresponding Euler equations. It was shown that the numerical results are partly consistent with the analytical predictions. The shock instability, however, was not always well simulated by the TVD-scheme., 資料番号: AA0000294020, レポート番号: NAL SP-30},
