Abstract

The present numerical investigation of the effect of porous surfaces on transition in hypersonic boundary layers is intended to improve understanding of the physical mechanisms and to provide numerical tools for the prediction of the associated delay in transition. Direct numerical simulations are carried out by a 4th order version of the DLR-Flower code, compared with the results of linear stability theory. Good agreement of both approaches and an accurate prediction of the damping of the Mack-mode instability which is responsible for supersonic transition is demonstrated.
