Numerical computations of hypersonic boundary layer roughness induced transition on a at plate

摘要

The work is focused on numerical simulations of roughness induced transition forhypersonic ow on a at plate wall mounted roughness element. Numerical simulationsare compared to experimental results in order to resemble the physics highlighted in thetests. In particular, stress has been placed on the detection of the vortices in the wakebehind the roughness element and on the onset of transition.
