- W2327117979 abstract "The results of the investigation of the noise characteristics of the exhaust jets from coannular nozzles with conventional and inverted velocity profiles are presented. Experiments were carried out on a series of coannular nozzles of equal primary and secondary area. The results of this study show that at high thrust level the coannular flows with inverted velocity profiles are quieter than those with standard velocity profiles at the same thrust and the same mass flow. The acoustic differences are much greater when the velocity ratio is produced by differences in the stagnation temperature rather than by differences in the stagnation pressure. Nomenclature A = area a0 = ambient speed of sound D = diameter / = sound intensity IL = intensity level m = mass flow rate P = pressure R = radial distance Th = total thrust U — local mean velocity u' — turbulence velocity V — jet-exit velocity B = polar angle measured from flow axis II = pressure ratio, P0/Pa p = density Subscripts a = atmospheric c = convection e = exit 0 = stagnation or ambient p = primary 5- = secondary" @default.
