This document explores a fluid instability known as buffet, which occurs in the subsonic, transonic and supersonic/hypersonic regimes. Buffet has been observed in experiments and various computational studies, and yet its underlying physics are not well-established. The goal of this study is to provide insight into various configurations which produce subsonic buffet and attempt to understand the flow physics at play. Both Reynolds Averaged Navier Stokes (RANS) and Direct Numerical Simulation of the Navier Stokes Equations (DNS) simulations were performed. Preliminary results for the study of transonic buffet over a range of angles of attack are also presented.
