Shape of the subsonic part of a nozzle with a flat acoustic surface with allowance for viscosity in the boundary-layer approximation

A numerical construction is proposed for the shape of the wall of the subsonic part of a nozzle. The design realizes nonseparated flow with an absence of local supersonic zones. The method is based on the simultaneous numerical solution of boundary-layer equations and equations of motion of an inviscid gas.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 42, No. 5, pp. 724–729, May, 1982.
