Triple deck solutions for supersonic flow past obstacles

ORAL

Abstract

This study is based on the numerical investigation of the boundary-layer separation of supersonic flow at high Reynolds number past obstacles (flat plate with a hump) based on the concept of viscous-inviscid interaction. The ``triple-deck'' model is used to describe the interaction process. We observe a separation region both ahead and behind the hump whereas a separation region is centered for the indents. In case of humps, at higher values of hump height, the pressure has both positive and negative value of ``plateau'' (observed up to now only upstream wedges). This novel feature has been compared with the ``interacting boundary-layer'' model which shows an excellent agreement.
