Dr Atkins' research interests are in the field of aero-thermodynamics, predominantly for gas-turbine engines. The research is multi-disciplinary, with a mixture of both experimental and numerical investigations. In general, the research is focused on finding the fluid physics missing from current design systems, and to work out the best way to measure and model the phenomena. Often, the work is focused on long standing issues where there is a lack of current understanding. The wider aim is to help improve the reliability and fuel efficiency of the next generation of machines. Current projects include the effect of rotationally dominant flows on the design of gas turbine secondary air systems. Much of the research in recent decades has made a quasi-2D assumption about the flow structures within the various cavities of a gas turbine engine which limits manufactures' ability to predict the metal temperatures in many critical regions. As such, the design of new engines (both for propulsion and power generation) often features multiple empirical design iterations due to hot-section failures. Simple numerical studies have highlighted many 3D flow phenomena and a test facility is being built to confirm the physical mechanisms. Dr Atkins is also interested in aero-thermal instrumentation development and is currently developing IR techniques for the study of transition and heat transfer in engine-representative conditions.
