 note = {この報告は衝撃波と粘性層との干渉を含む超音速乱流剥離-再付着流の実験に関するものである.後向きステップ後流の静圧,ピトー圧および淀点温度が測定され,流れ場のマッハ数,速度および密度分布が求められている.ステップ直後の剥離領域では粘性層をよぎる圧力勾配はかなり小さいけれども,干渉領域では衝撃波はその圧力上昇を連続的な圧縮波の形で粘性層の内部に影響をおよぼしており,そこでは粘性層をよぎる圧力勾配は必ずしも小さくないことが示されている。しかし,この影響範囲は粘性層の上部に限られており,下部では圧力勾配はかなり小さいことが明らかにされている.干渉領域の後流では静圧が一様流のそれにほとんど回復し,かつ粘性層の至る所圧力勾配は無視できるほど小さいにもかかわらず,粘性層下部の速度は平板流の速度プロフィルに比較して回復が遅れていることが示されている., This report is concerned with an experimental investigation of supersonic turbulent separated-reattaching flow involving the interaction between a shock wave and a viscous layer. Measurement of static pressure, pitot pressure and stagnation temperature is made at free stream Mach number of I .94 in the region downstream of a rearward-facing step and distribution of local Mach number, flow velocity and density is obtained. It is shown that the transverse pressure gradient is small in the separated region while, in the recompression region, the shock wave is diffused into the viscous layer in the form of continuous compression waves, inducing a fairly large pressure gradient there. However, the region of shock wave influence is found to be restricted to only upper part of the viscous layer and the pressure gradient in the lower part is revealed to remain relatively small. Finally, it is pointed out that, just downstream of the interactioh region where the static pressure has recovered to its free stream value and the pressure gradient is negligible throughout the viscous layer, recovery of flow velocity in the lower part of the layer does not yet attain to the velocity profile corresponding to flat plate flow., 資料番号: SA0124543000},
