Stabilization of a two-dimensional supersonic jet flow for different physical properties of the outflowing gas and the gas in which the jet is submerged
Abstract
The space-time dependences of the motion of the starting shock wave and the contact surface inside the nozzle and into the space in which the jet is submerged are determined experimentally for the pulsed starting of two-dimensional supersonic jet flows of different gases (gamma = 1.16-1.67) in a wide range of pressure differences (p sub 0/p sub infinity = 25-1700) and acoustic-velocity ratios (alpha sub 0/alpha sub infinity = 0.2-3.9) in the outflowing gas and the gas in which the jet is submerged. Dimensionless coordinates are introduced which make it possible to construct generalizing space-time dependences of the motion of the starting shock wave and the contact surface. The effect of the physical properties of the submerging gas on the displacement velocity of the starting gasdynamic discontinuities is analyzed.
