Expert in Fluid Flow Systems/Heat Transfer Equipment/Porous Media Flows/Thermal Management
For their application to complex flow fields such as gas and liquid jets, channel flow design, turbulence, flow separation and mixing processes, and micro-scale fluidic systems.
NEWTONIAN FLOW. Both experimental and computational methods have been used by Expert to study internal and external flows of Newtonian fluids. Some emphasis has been in the area of drag and pressure drop reductions.
INTERNAL FLUID DYNAMICS. Expert has done extensive experimental and numerical simulations of two- and three-dimensional flows with and without heat transfer and has helped design micro-fluidic systems.
COMPUTATIONAL FLUID DYNAMICS; TURBULENT FLOW. Expert has developed two and three dimensional codes for the solution of laminar and turbulent flows. He has played a large role in advancing turbulence models for complex flows. He has also used several of the existing commercial codes, modifying them for complex three dimensional and transient applications.
FLUID FLOW MEASUREMENTS. Much of Expert's recent career has been devoted to developing new optical instrumentation methods for highly accurate fluid flow measurements. His experience includes Laser Doppler anemometry, hot wire anemometry, holographic imaging, PIV, and several flow visualization techniques.
CONVECTIVE HEAT TRANSFER; FORCED CONVECTION; HEAT CONVECTION. Expert has studied convective heat transfer for over 20 years, and has written more than 50 technical papers in the field. Recently he has focused on transient forced and natural convection problems with application to high heat flux conditions. New methods have been studied, such as surface geometry modifications, to enhance convective heat transfer.
NUCLEAR REACTOR FLOWS. Expert has set up and studied flow enhancement in nuclear rod bundles. This work includes pressure drop, flow visualization, and velocity measurements.
DYNAMIC HEAT TRANSFER. Dynamic heat transfer effects have been a part of Expert's research, especially relative to external surfaces with time dependent heat generation.
EJECTOR PUMPS. Expert has experience designing and testing several types of ejector pumps used in major national laboratories for transport of hazardous fluids. He has also designed and tested two-phase supersonic nozzles and diffusers used in ejector pumps, and has developed models for two-phase flow operation.
AIR EJECTORS. Expert's research has involved new designs and testing of air and water ejectors for multi-phase pump applications.
OPTICAL INSTRUMENTS; INTERFEROMETER. Much of Expert's research over the past 15 years has been in the development of new optical methods for the Measurement of fluid flow and heat transfer. He has designed and implemented two and three dimensional interferometers for fluid flow and heat transfer measurements.
FLOW VISUALIZATION. Expert has used novel visualization methods (based on holographic imaging and other methods) to study single and multi-phase flows.
