Abstract

The outlet cross-sectional area of standard nozzle affects the air mass flow value of TPS. Through the jet simulation of three standard nozzles with different outlet sizes under different boundary conditions, the relationship between outlet diameter and boundary conditions and jet turbulence intensity and near-field and far-field noise is studied. The simulation results show that the outlet cross-sectional area affects the value and range of the turbulence intensity, and has a great change in the mixing region of the turbulent boundary layer. However, under the excitation of the sound source quadrupole, it has no great impact on the propagation trend and extreme value of the sound wave.
