Design of Water Tunnel to Measure Wall Pressure Signatures Due to Tunnel Blockage and Wake Effects

Abstract

This thesis describes the design and construction of a new test section for the AFWAL Aero Propulsion Lab six-inch water tunnel in building 18. The new test section has a ten-inch square cross section and is designed to measure wall pressure signatures caused by solid and wake blockage of the flow due to the separation bubble which forms around bluff bodies immersed in the flow. The wall pressure signature for a spherical model is predicted. Applications of the method and associated requirements for instrumentation are discussed. Theses.
