My research focuses on the fields of combustion, propulsion, and fluid mechanics, and the development of optical diagnostic techniques and sensors for application to these fields. My students and I have authored roughly 150 papers in these areas. Our current research activities include: determination of flame speeds for syngas (CO/H2/CO2/N2/H2O) and hydrocarbon fuels at gas turbine conditions (elevated pressures and temperatures); lean blowout detection sensors for gas turbine combustors; development of the stagnation-point, reverse-flow (SPRF) combustor for low emissions and flexible fuel applications; characterization of flame chemiluminescence sensing for heat release and fuel-air ratio measurements; velocity and multiscalar measurements for validation of combustion CFD models; development of Raman scattering measurements in high pressure combustors; development of optical absorption and emission sensors for active control and health monitoring of combustors in practical devices like turbine engines. Other recent efforts include: planar laser-induced fluorescence (PLIF) of ketones to characterize fuel-air mixing from gaseous and liquid fuels, and tocharacterize trans/supercritical mixing in coaxial (rocket) injectors; development of laser-induced incandescence (LII) for the in situ measurement of soot in combustors and engine exhausts; soot studies in acoustically forced combustors and flames; synthetic jets to control fuel-air mixing; combustion of nanoscale metal particles; measurements of fuel condensation in supersonic nozzles; oxide residue characterization for aluminized solid propellants; and measurements and modeling of near surface combustion processes for understanding plateau burning in bimodal, composite AP/HTPB solid propellants. In addition, I have supervised a number of undergraduate research teams participating in microgravity research.: GT Undergraduate NASA Reduced Gravity Flight Opportunities Teams
