Abstract:

The purpose of this instrumentation grant was to purchase equipment to be used in conjunction with an ongoing ARO-funded research grant entitled Experimental Studies of High-Speed Separated Flows. The research efforts of this program are focused on experimental investigation of the fluid dynamic mechanisms and interactions within separated flow regions embedded in high-speed compressible flows. The fundamental objective is to improve understanding of the detailed flow processes in the near-wake of missile and projectile-type base flows with the long-term goal of optimizing and controlling these flows to derive flight vehicle performance benefits. The funds were used to repair the heads of two NdYAG lasers that are used heavily in particle image velocimetry, RayleighMie scattering, and planar laser-induced fluorescence PLIF experiments. These replacementsrepairs will extend the lives of these lasers for at least 5 years. The department also used the equipment funds to purchase an intensified CCD array camera system that may be used for experiments with low signal levels e.g., for ongoing acetone PLIF experiments. Finally, funds were used to purchase a state-of-the-art pressure transducer calibration dead-weight tester. In all cases, purchase of this equipment will help to maintain and strengthen the departments ability to make significant contributions to the research area of compressible, separated flows, which is of significant importance to the U.S. Army. The specific pieces of equipment, vendors, and purchase prices are detailed.
