Study of a Viscous Sublayer Model in the Analysis of 3-D Shock/Boundary Layer Interaction Flow Fields

Abstract

At high Reynolds number, it has been experimentally and computationally well-confirmed that the 3-D interactive physics is vertically organized into the triple-deck type of structure. The governing integral-type equations that characterize the non-reversed flow portion of the interactive wall layer model are formulated in the form of a set of nonlinear partial first order differential equations, including three-dimensional aspects. Also modeled was the splitting of the layer into an upper region of non-reversed flow and an underlying region of slow, reversed flow. The shock structure and nonlinear rotational inviscid flow behavior of the overlying region were explored by means of a suitable 3-D shock/boundary layer approach which include separation. The NASA Langley code 'Laura' was modified to include these new wall layer equations.
