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…
