SECONDARY FLOW REVERSAL AND VELOCITY PROFILE MODELS IN A THREE-DIMENSIONAL TURBULENT BOUNDARY LAYER.
Abstract
The results of an experimental program are reported, wherein the secondary or lateral flow in a three-dimensional turbulent skewed boundary layer inside a recurving duct was made to reverse itself completely. In such a reversal process there occurs a region of flow where the boundary layer experiences lateral flow in two different lateral directions simultaneously. The physical arguments which support the existence of such flow regions with simultaneous lateral skewing are discussed and supported by the experimental results. Several of the more recent velocity profile model which are intended for use in describing skewed turbulent boundary layer flows are reviewed as to their applicability to a flow with such simultaneous lateral skewing.
