Shock wave interactions are important in a variety of engineering applications, ranging from gas turbines to rocket nozzles. There is much discussion regarding the sources of unsteadiness related to unsteady shock wave structure. This thesis investigates related interactions through spectral analysis of shock wave tracked positions, and instantaneous surface static pressure, temperature, and heat flux. A shadowgraph system for implementing shock wave tracking analysis is employed within a supersonic test section with an inlet freestream Mach number of 1.54. Unsteady surface static pressure and temperature variations are measured at streamwise locations along the bottom wall. Unsteady temperature data are used to determine surface heat flux variations. Pressure, temperature, and heat flux variations are correlated to the position of the normal shock wave through magnitude squared coherence and time lag. Data show complex physical variations that change as frequency, inlet turbulence intensity, and location relative to the shock wave are altered.
