    Abstract
  • Experimental study of supersonic jet flow using digital PIV system with frame straddle CCD camera is introduced in the paper. The diameter and Mach number of the Laval nozzle exit are 13.8mm and 1.5 respectively, the vector field and wave patterns of the jet flow in different pressure ratio of the stagnation pressure with the surrounding static pressure were observed. The results show the different of flow speed and other parameter of flow field before and after the shock wave. The generation of particles and seeding method are also simply described in the paper.
