Following is a summary of Dr. Hassan’s current projects:
Gas Turbine Macro and Micro Cooling:
Advanced and innovative cooling techniques are essential for further improvement in the efficiency and power output of gas turbines. Dr. Hassan’s projects focus on the development of advanced cooling schemes for the next generation of gas turbines, by providing detailed experimental and computational investigations of its heat transfer and fluid mechanics. He designed and constructed state-of-the-art heat transfer test facilities using the liquid crystal thermography for heat transfer measurements and stereoscopic particle image velocimetry for flow structure measurements. Dr. Hassan has also performed fundamental studies related to heat transfer and aerodynamics of turbine cooling, e.g., 1- effects of turbine inlet temperature on rotor blade tip leakage flow and heat transfer, 2- rotational effects on film cooling, 3- unsteady heat transfer analysis of film cooling flow, and 4- effects of shock waves on film cooling performance. Pratt and Whitney Canada, Natural Sciences and Engineering Research Council of Canada, Canada Innovation for Foundation, and Synergetic Research and Innovation in Aerospace, provided the external support for Dr. Hassan’s projects.

Micro thermal and fluidic devices will continue to become an integral part of today’s postmodern society. With the progression of technology comes the demand for smaller devices to perform the work needed in a complex device. Examples include micro heat sinks for electronics cooling, and lab-on-a-chip for medical drug discovery process. It is imperative that the fluid mechanics and heat transfer in these micro devices are clearly understood for the development of such systems. Dr. Hassan has focused in his research projects on fundamental issues related to heat transfer mechanisms in micro-devices, which require high heat transfer rates within a small footprint area, e.g., 1- flow regimes and pressure drop in micro-channels, 2- two-phase flow instability in microtubes, 3- dry-out incipience for flow boiling in micro-channels, and 4- turbulent heat transfer in the thermal entrance region of micro channels.
