Book Description
The goal of this project was to establish a datum for acoustics generated in an exhaust flow from a jet pipe, due to the presence of an opening with a hatch at an angle, by using the Computational Fluid Dynamics (CFD) tool FLUENT. After validating the geometry using a supersonic case employing a fully expanded jet, a secondary supersonic test case was produced to compare results with the former using a Detached Eddy Simulation with Spalart-Allmaras (DES-SA) scheme. Two subsonic cases using the same boundary conditions (BCs) were then computed using a Large Eddy Simulation (LES) turbulence model in order to solve for flow-field data and Sound Pressure Level (SPL) of the given geometry. Focus was given to the region around the opening, and the computed pressure data was stored in three regions: above the opening, under the opening, and past the opening. Pressure contours in the region around the hatch were captured well and shown to be consistent between the two geometries employed for the domain of solution. Results concluded that using the smaller domain of solution maintained resolution quality while decreasing overall computation time tremendously.
