Plane underexpanded jet flowing out at an acute angle to a confined cross flow

The propagation of a sonic jet at an acute angle to a subsonic cross-flow induced by the jet itself is investigated experimentally. The dependence of the extent of the circulation zone and the rarefaction behind the jet on the degree of confinement of the cross-flow and the relative total pressure in the jet is found. The jet ejection properties is studied.Moscow. Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No. 5, pp. 66–71, September–October, 1995.
