断面積一定の管内における擬似衝撃波の一次元流れモデル

抄録

One-dimensional flow model for a pseudo-shock wave in a constant-area duct is presented where the boundary layer at the initial section of the pseudo-shock region is considered. The conservation equations of mass, momentum and energy across the pseudo-shock are treated one-dimensionally by assuming an appropriate mean flow over a given cross section of the flow. For given conditions upstream of the pseudo-shock, the characteristic properties through the pseudo-shock such as the downstream Mach number and the static and stagnation pressure ratios across the pseudo-shock calculated using the present model agree well with the previous experimental results.
