HYPERSONIC STUDIES OF WAKES BEHIND CYLINDERS. PART I: PITOT PRESSURE MEASUREMENTS AT M = 16 IN HELIUM,
Abstract
The pitot pressure was measured in the wake of two-dimensional circular cylinders at a Mach number of 16 in helium. The diameters of the cylinders used were 1/8 inch and 3/16 inch giving a Reynolds number variation of 10,500 to 25,300 based on free stream conditions. Surveys were performed as far back as 80 body diameters. Profiles in the far wake at the same x/D were similar, independent of body Reynolds number. The wake growth was found to vary as the 0.6 power. Body Reynolds number had no effect on the rate of growth over the range studied. It was not possible to deduce transition from the pitot pressure measurement alone. (Author)
