Direct numerical simulation is used to study flow over a roughness element in a flat plate boundary layer at high speed. The roughness element is modeled as a continuous bump with a height that is approximately half the boundary-layer thickness. Simulations with a variety of Mach numbers and wall temperatures have been run over a range of Reynolds numbers, and the results are used to establish a criterion for turbulent breakdown.
