Abstract
Using the numerical solution of the Navier-Stokes equations, the development of unstable disturbances and the transition to turbulence in a simulated supersonic jet flowing from a circular supersonic nozzle were studied. The simulation was performed in a three-dimensional formulation with resolution of the vortex structure of the flow. The results of numerical simulations were compared with available experimental data.
