N2 - Numerical simulations of inlet buzz are performed to find effects of computational parameters, i.e., the maximum limit of sub-iterations, the grid density, and the time-step size on buzz frequency. An axisymmetric supersonic external compression inlet is chosen as a simulation model. Simulations are carried out using an axisymmertic Reynolds-averaged Navier-Stokes solver with Menter's k- ω two-equation turbulence model. Convergence of the buzz frequency is systematically studied with the computational parameters. Through results of the study, proper computational parameters to obtain a converged buzz frequency are determined.
