A Study of Mach 0.75 Jets and Their Radiated Sound Using LargeEddy Simulation
"... LargeEddy Simulations (LES) of a compressible nozzle/jet conguration have been carried out. Two jets were simulated, an isothermal jet and a jet with a higher temperature than the quiescent surrounding air. The Mach number was in both cases 0.75 and the jet Reynolds number was 5.0 10 . Sound pres ..."
