Abstract: | A method of theoretical investigation of the flow field in a two-dimensional (plane-parallel or axisymmetric) overexpanded
jet of an ideal perfect gas in the vicinity of the nozzle lip is described. The changes in curvature of the shock wave emanating
from the lip, as well as the shock-wave intensity and flow parameters behind the shock are analyzed as functions of the Mach
number, pressure ratio in the plane jet, and ratio of specific heats of the gas.
