Expertise

  • Traditional Heat Transfer and Fluid Mechanics Investigations involving electronics cooling, heat transfer augmentation, drag reduction, turbulent boundary layers, flows in channels with dimpled surfaces, flows in curved channels, elastic turbulence, slot impingement cooling, and macro-scale pumps and pump flows. Also included are aerodynamics investigations with high- speed, compressible flows at transonic and supersonic Mach numbers, including SWBLI – Shock Wave Boundary Layer Interactions. Related projects involve transonic and supersonic experimental testing. Research interests also include experimental diagnostics in high speed flows, and air breathing propulsion.
  • Air Breathing Engines - Gas Turbine Heat Transfer, Cooling, and Aerodynamics Losses, including internal cooling, film cooling, impingement cooling, cooling of extremities, aerodynamic performance including aerodynamic losses, and transonic turbine flows and heat transfer. This subject area includes the effects of uses of bio-fuels, synthetic fuels, and renewable energy sources in relation to gas turbines and gas turbine heat transfer and cooling technologies. Note that an important area of turbomachinery research interest involves heat transfer and aerodynamics investigations with high-speed, compressible flows at transonic and supersonic Mach numbers, including linear cascade studies.
  • Micro-Fluidics and Millimeter-Scale-Fluidics, including micro-pump flows, and the effects of slip phenomena on gas and liquid flows in micro-scale passage flows with and without surface roughness, including the effects of hydrophobic surfaces and elastic turbulence.
  • Experimental Techniques, including development of millimeter-scale multiple-hole pressure probes, subminiature hot-wire anemometry, and infrared thermography.
