My Research: My current general research area is related to thermal management in gas turbine components and aerospace systems. The main focus at this stage is towards the development of new advanced cooling techniques for gas turbine blades and micro thermal management devices for avionic systems. Further, conduct interdisciplinary research on the effects of manufacturing techniques on thermal performance of micro-thermal management components.


bullet FILM COOLING OF GAS TURBINE BLADES

The development of a new generation of high performance aircraft turbine jet engines requires gas turbines to be operated at very high turbine rotor inlet gas temperatures. The overall goal of this research is to develop innovative cooling techniques for gas turbine blades. The objectives of the current film cooling research project include: (1) Assessment of the potential of various turbulence models: k-e, k-w, Reynolds Stress Model (RSM), and stochastic turbulence models such as Detached Eddy Simulation (DES), Large Eddy Simulation (LES) and Shear Stress Transport (SST) models, to predict and capture the signature of the film cooling flow. (2) CFD simulations to study new concepts to control vortices and coolant jet spreading in the vicinity of the holes. 3) Assessment of CFD as a tool to predict the effects of surface roughness on film cooling. (4) Experimental investigations of the effects of injected coolant supply systems and jet vortex control, on film cooling and heat transfer for unconventional shaped-holes. 

         Manufacturing and testing of micro-heat exchangers for cooling of gas turbine blades are also underway.

ELECTRONIC COMPONENT COOLING

Heat transfer in electronic components continues to attract a lot of research activity towards achieving better cooling techniques to meet the design and development of rather complex circuits and dense electronic boards, characterized by high rate of heat dissipation per unit of component area. The topography of the electronic board plays a significant role on the heat transfer and pressure drop characteristics of theses boards.

This project  investigates innovative techniques for cooling electronic components with particular applications to aerospace systems.
