Three-Dimensional Viscous Interactions,
Abstract
The paper presents results of analysis and experiment bearing on three-dimensional effects in hypersonic interaction, with emphasis on a sharp-edged rectangular corner intersection aligned with the flow and a sharp-edged plate of finite span. A powerful tool for dealing with such complex problems is the 'merged-layer approximation' which obviates the need for complicated matching procedures in many instances of importance although numerical computation is required. This type of flow, in which various elements are strongly coupled and even merged, is shown to have features in common with low-speed three-dimensional boundary layers such as those along an interior corner or along the edge of a quarter-infinite plate. In the low speed cases the essential viscous-inviscid interaction coupling enters through the weak, Reynolds-number dependent, displacements of the inviscid flow which must be taken into account even to lowest order. The attendant analytics and numerics are in many respects more difficult to deal with than those of the hypersonic counterparts. (Author)
