THE THREE-DIMENSIONAL WAKE BEHIND AN OBSTACLE ON A FLAT PLATE,
Abstract
An investigation of the three-dimensional, incompressible wake behind a blunt obstacle located at the leading edge of a flat plate is presented. Configurations studied included the 'clean' flat plate, and the flat plate with a rectangular, a square, or a two-dimensional obstacle fitted to the leading edge of the plate. Experimental results are compared to a mathematical model based on the Oseen linearization for diffusive flows. Based on mean flow measurements, a transition to turbulent flow was not encountered for any of the configurations examined. Such wakes are characterized by a region of strong vorticity immediately behind the obstacle followed by a region of viscous dissusion. Bulk properties of the wake-like flow and the applicability of the theoretical model were found to be highly dependent on the geometry of the obstacle. (Author)
