摘要：
The steady-state structure of supersonic underexpanded jet flow at Ma = 1 is experimentally investigated. The measured total pressure distributions are presented in different cross sections and along the jet axis. Certain distinctive features of the supersonic jet flow are revealed. Among these are considerable fluctuations of the density distribution in the mixing layer formed behind the triple point on the normal shock in the jet. They are due to the presence of vortex structures in the internal mixing layer. The data obtained are used in testing the results of numerical calculations.
