SUMMARY OR ABSTRACT
Text of Note
High-speed flow is an active area of research with applications in defense, space exploration, and aviation. To better understand the physics of such flows, a measurement technique called Krypton Tagging Velocimetry (KTV) is developed in this work. KTV is a laser diagnostic technique that uses the fluorescence of excited krypton atoms doped in a gas of interest to measure flow velocity. The inert nature of krypton makes KTV an attractive tool in applications where the chemical composition is difficult to prescribe or predict, and unlike particle-based techniques it does not suffer from particle-lag effects. Various versions of KTV are presented, the differences among which include excitation wavelength and the number of lasers required. To demonstrate its utility, KTV is applied to four canonical compressible flows; an underexpanded jet, a supersonic boundary layer in an impulse facility, a hypersonic nozzle flow, and supersonic compression-corner flow. In many cases, data from the literature are used to validate the use of KTV. Furthermore, the data from the compressioncorner experiments are used to perform an in-depth analysis of shock wave/turbulent boundary-layer interaction (SWBLI). This analysis includes the characterization of the turbulence intensity and the use of proper orthogonal decomposition (POD) to identify flow structures. In addition to the analysis, preliminary two-dimensional KTV (KTV-2D) results for the compression-corner experiments are presented.
