TALK=T;RUN(1,1) DISPLAY The problem considered is the near-field of a sonic under- expanded turbulent round jet issuing into stagnant surroundings. The stagnation enthalpy of the nozzle fluid is equal to that of the free stream, so that with the assumption of unit Prandtl numbers the energy equation need not be solved. The turbulence is represented by the k-e model, and the IPARAB=5 option of the parabolic solver is used to perform the marching integration. The calculations are started at the jet discharge plane, and carried out until 6 diameters downstream. The calculations are made with 35 radial grid cells and a forward step size of 1% (DZW1) of the local grid width. The main input parameters are the inlet and free-stream Mach numbers and the jet-to-ambient static pressure ratio. This case has been tested for inlet Mach numbers up to 2 and pressure ratios up to 2.5.
