Research Summary

Professor Sam Sampath is a specialist in combustion and emissions, applicable to aviation gas turbine engines. With Pratt and Whitney Canada (P&WC) from 1970 to 2011, Dr. Sampath helped to create the combustion systems of a large number of aviation gas turbine engines currently in field operation, or going through development for application to future aircraft. During his tenure at P&WC, Dr. Sampath played the dual role of manager and Senior Fellow on Combustion. He led several research programs on ultra low emission technologies, alternative and bio fuels. His international research collaborations included US, European, and Indian universities and research institutions. He is author or co-author of over thirty-five papers/publications and innumerable industrial research reports of a proprietary nature. Dr. Sampath also contributed to the latest version of the Handbook of Fluid Dynamics. His environmental impact studies contributed to the 2007 Nobel Peace Prize award to the Inter-governmental Panel for Climate Change (IPCC). Dr. Sampath has been awarded fourteen international patents, a Fellowship of the Canadian Academy of Engineering (FCAE), and a P&WC pioneer award for lifetime achievements.

Over the last sixty years, aviation has evolved in a steady manner with improvements of aircraft/aero-engine efficiency, performance, reliability, range, specific power, etc. This evolution has been facilitated by the availability of engineers and scientists from Canada and abroad including aerodynamicists, structural and other system engineers in many disciplines. New environmental challenges in the future include green engine designs with major reductions of harmful pollutants such as oxides of nitrogen, carbon monoxide, and particulate emissions. The other major demand is the need to reduce the carbon footprint by reducing Green House Gases (GHG). These needs have resulted in the creation of a UTIAS Executive Industrial Research Chair for Dr. Sampath, supported by NSERC and Pratt and Whitney Canada. The focus of Prof. Sampath’s efforts is to support specific combustion and emission projects along with three other professors and some graduate students. The aim is to advance the capabilities of UTIAS to become the centre of excellence in the fields of aviation gas turbine combustion and emissions.
