Personal profile

Research interests


Dr Carl Sangan is a Reader (Associate Professor), Director of Research and the Deputy-Director of the Turbomachinery Research Centre within the Department of Mechanical Engineering.

His research area is gas turbine engineering, with a particular interest in experimental and theoretical modelling of the flow and heat transfer in rotating disc systems.

Carl obtained an MEng (Hons) in Aerospace Engineering, followed by a PhD in the field of turbomachinery. On graduation he continued as a post-doctoral researcher, before being awarded the University Prize Fellowship in Gas Turbine Engineering in 2012. Carl became a lecturer at the University in 2014, Senior Lecturer in 2017 and Reader in 2020.


Carl's current research focuses on improving the efficiency of gas turbines for power generation and aerospace engines. He currently leads research programmes involving the application of optical methods to enhance understanding of the interaction mechanisms between gas turbine cooling systems and the mainstream gas-path.

Although predominantly funded by EPSRC, much of his work is closely linked to Siemens and Safran Aircraft Engines, where modelling approaches developed from the work are being integrated directly within the design methodology employed at the companies.

Areas of interest across the broader theme of turbomachinery include:

  • modelling of hot-gas ingestion through turbine rim seals
  • mainstream gas-path aerodynamics and the interaction with the secondary air system
  • heat transfer in compressor cavities
  • development of novel shaft sealing technologies
  • film cooling of turbine blades
  • cooled radial turbomachinery
