Effect of local porous coating on the stability of boundary layer

Abstract eng:
A local scattering approach (LSA) was introduced to study the effect of local porous coating on the stability of an incompressible boundary layer. The prediction by LSA was verified by direct numerical simulation (DNS), and was compared to that by linear stability theory (LST) in order to check the validity of the latter. A systematic parametric study was performed, and the results show that local porous coating significantly enhances Tollmien-Schlichting (T-S) waves, and the effects can be quantified naturally by a transmission coefficient, which is an intrinsic physical property of the problem.
