The Investigation of the Propagation Mechanism of Pressure Fluctuation in Turbulent Flow.

Abstract

A one foot induction wind tunnel was built for the purpose of studying the coherent structure of turbulence. Simultaneous measurements of velocity, wall pressure and wall-shear fluctuations were made on the wall of a one foot pipe in a range of velocities from 30 to 700 ft/sec. The results presented here were obtained for flow conditions which differ significantly from those in previous studies. For the majority of the tests, the free stream velocity is in the high subsonic regime, and the Reynolds number is an order of magnitude higher than that for which the coherent structure has previously been investigated. The measurements were made on the wall of an axially symmetric one foot test section in order to insure true two-dimensionality of the flow.
