Summary of Research:
My dissertation research involves advanced optical diagnostic techniques to obtain phase and velocity profiles in gas-solid flows. More specifically, I am characterizing a horizontal gas jet penetrating a bubbling fluidized bed. I am developing a laser induced fluorescence (LIF) probe to determine phase concentrations and I am using laser Doppler velocimetry (LDV) techniques to obtain velocity measurements. The data obtained from these experiments will be used by a collaborating computational fluid dynamics (CFD) group, which will ultimately yield more robust design tools for multiphase flow systems.
