Measurements in the Turbulent Boundary Layer of a Yawed, Spinning Body of Revolution at Mach 3.0 with a Laser Velocimeter and Impact Probe.

Abstract

This paper presents measurements which were made in the turbulent boundary layer on a spinning projectile shape with a flattened impact pressure probe and with a laser velocimeter. Comparison of these measurements shows that the LDV can be successfully used to obtain accurate measurements of the three-dimensional turbulent boundary layer and provides confidence that the LDV can be used in flow situations that are not practical for impact probes.
