2346 溝付き壁を有する管路を伝ぱする弱い衝撃波に関する数値解析(S46-4 圧縮性流れの基礎と応用(衝撃波2),S46 圧縮性流れの基礎と応用)  [in Japanese] 2346 Numerical Study of Weak Shock Propagating in the Duct with the Ditched Wall  [in Japanese]

In this paper, the attenuations of weak shock waves propagating in the duct with the ditched wall were investigated numerically. The computations were carried out by solving the two dimensional compressible Navier-Stokes equations by using total diminishing variation (TVD) scheme. The effects of attenuation of the shocks by the ditched wall were clarified by various diagrams.
