Influence of wall thermal boundary condition on mean-flow characteristics of a Mach 2.5 fully rough turbulent boundary layer
Mateus A. R. Braga, Robyn L. Macdonald
We investigate turbulent boundary layers at Mach 2.5 over sinusoidal roughness at matched . We considered three wall temperatures, 1.0, 0.7, and 0.4. Each wall…

Distributed Roughness-Induced Transition on a Blunt Body at Mach 6: a Numerical Investigation
Sean Dungan, Mateus Braga, Robyn Macdonald +1
Surface roughness significantly impacts transition to turbulence, especially over high-speed, blunt geometries where surface ablation is necessary to mitigate heat loads during atm…

Demonstration of an integral method for estimating wall shear stress in complex high-speed flows
Mateus A. R. Braga, Robyn L. Macdonald
Turbulent flows over blunt bodies with distributed roughness present a class of problems relevant to hypersonic atmospheric entry systems. However, accurate predictions of shear st…
