Flow Characterization of the Trisonic Gasdynamics Facility Using a Laser Velocimeter

Abstract

The need for good tunnel calibration data is ever present for the experimenters. Current requirements by investigators in the Trisonic Gasdynamics Facility (TGF) have been including laser Doppler velocimeter (LDV) measurements more routinely. Therefore, a reasonable degree of confidence in the LDV measurements requires some baseline data from the facility with no model in the flow. To this end an entry was made the summer of 1984 exclusively for LDV analysis of the flow. The tunnel was run with the wooden nozzle blocks installed. Several Mach numbers were run for wall boundary layer and free stream measurements. In addition, during an entry in November 1984, several boundary layer profiles were taken at Mach 0.3 for comparison with the wood nozzle data, while the steel subsonic blocks were installed.
