Quasi-Three-Dimensional Supersonic Viscid/Inviscid Interactions Including Separation Effects.
Abstract
This study is concerned with viscous/inviscid interactions in two and quasi-three-dimensional supersonic flows with separation. Interaction effects are modeled through the so called 'displacement body concept', wherein it is assumed that the inviscid flow 'sees' an effective body obtained by adding the displacement thickness to the original surface. The governing equations in the viscous region are taken to be the interacting boundary-layer equations and an alternating-direction-implicit (ADI) finite difference scheme is employed to obtain their solution. This technique is applied to the quasi-three-dimensional problems resulting from flow past swept (yawed) and axisymmetric compression surfaces. Detailed distributions of surface pressure, skin friction and heat-transfer are presented for Mach numbers of 2 to 6. It is found that both cross flow and axisymmetric effects are easily accommodated in the solution technique and that the predicted results are in qualitative and quantitative agreement with available experimental data.
