Research Interests
- Cavitation phenomena, attached partial cavitation, cavitation in turbulent shear flows, jets and wakes.
- Multiphase flows: Interaction between bubbles and flow structure, mixing mechanisms and droplet formation in water-fuel stratified shear flows, transport of microscopic particles and droplets in turbulent flows.
- Development of optical flow diagnostics techniques, including Particle Image Velocimetry (PIV) and Holographic Particle Image Velocimetry (HPIV).
- Applications of PIV and HPIV for measuring the characteristics of turbulence and addressing turbulence modeling issues.
- Complex flow structure and turbulence within turbomachines: Wake-wake and blade-wake interactions in multistage axial turbomachines, flow and rotating stall in centrifugal pumps, development of optical diagnostics techniques for measurements in turbomachines.
- Oceanography: Flow structure and turbulence in the bottom boundary layer of the coastal ocean; measurement of spatial distributions of plankton, particles and bubbles in the ocean; development of optical instrumentation, including submersible holography and PIV systems.
- Prevention of nozzle wear in abrasive water suspension jets (AWSJ) using porous lubricated nozzles.
- Flow-induced vibrations and noise, mechanisms of noise generation in turbulent separated flows and in turbomachines.
