Research Topic

Study of two-dimensional and three-dimensional natural convective fluid flow in a cavity using non-intrusive schlieren technique. It is a refractive index based optical technique used to obtain both qualitative and quantitative information. Currently I am developing such an innovative stereoscopic schlieren technique based on conventional z-type schlieren system to study three-dimensional natural convective fluid flow. I have also worked on developing of theoretical model of heat engine cycles based on Finite Time Thermodynamics. In the model of an air standard irreversible Otto cycle model, the non-linear relation between the specific heat of the working fluid and its temperature, the friction loss computed according to the mean velocity of the piston, the internal irreversibility described by using the compression and expansion efficiencies, and the heat-transfer loss are considered. The heat leak rate between two reservoirs is considered for further analysis of irreversible Otto cycle. The effects of specific heats which are dependent on the temperatures of the model cycles are also studied.
