On the law of central shock displacement for an undersaturated jet affected by an obstacle

A generalized dependence of the dimensionless position of the central shock on the dimensionless position of an obstacle relative to the nozzle exit is obtained. The dependence is obtained for M _a =1.0–2.0 and uncalculability n=2.2–6.7 of the jet.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 18, No. 2, pp. 340–342, February, 1970.
