This research performed Reynolds-averaged Navier-Stokes (RANS) simulations for the flow past an aircraft protrusion mounted on a flat surface. The major factor in this research is the investigation of shock-wave/boundary-layer interactions (SWBLIs). RANS computations were performed using the Spalart-Allmaras turbulence model and a second-order Navier-Stokes solver. The two complex three-dimensional geometries primarily focused on in this research were the circular-arc bump antenna and the TT-5006A antenna. Numerical results were in good agreement with the wind tunnel experimental results; however, some discrepancies in the flow properties occurred at the shock-interaction region. Computations were performed using the commercial software computation fluid dynamics (CFD) tool FLUENT in the High Performance Computing Center (HiPeCC) at Wichita State University. / Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Aerospace Engineering
