An experimental study of pressure fluctuations in flow around a sphere
Abstract
Results of blowdown wind tunnel tests are presented for a 70-mm-diameter sphere for Mach 0.3-1.2 and 3. The Reynolds numbers, determined from the incoming flow parameters and sphere diameter, are (0.6-1.5) x 10 to the 6th. The relative pressure fluctuations, measured for different points on the surface of the sphere, are presented as a function of the Mach number of the incoming flow. The factors responsible for the observed pressure fluctuations are examined.
