Simulating Nozzle and Jet Flow for Supersonic Noise Reduction

This research update focuses on the numerical simulation of nozzle and jet flow for reducing supersonic noise. The study includes the configuration of two pairs of NACA0012 vanes at different azimuth and attack angles. The simulation method involves the use of 3D Reynolds-Average Navier-Stokes equations and the ParCAE CFD code. Various turbulence models are employed, including S-A and K-ω SST. The study also explores alternate K-ω models if necessary. The research extends to the simulation of B27 nozzle configuration with one pair of NACA0012 vanes at different azimuth and attack angles. Additionally, the generation of 3D fan nozzle grids is discussed.
