Academic Background

Professor Heyes studied Mechanical Engineering at the University of Manchester. He obtained a BEng degree in 1989 graduating with first class honours. He was also awarded the H.Wright-Baker prize for the best final year project: "An Investigation of Supersonic Jet Screech and Twin Plume Resonance". He then went on the obtain an MSc in 1991 and PhD in 1994, also from Manchester, for development of the laser based Doppler Global Velocimetry optical flow diagnostic technique and the application of optical techniques for 3-D velocimetry in the vortical flow around a lifting delta wing at supersonic speeds.

In 1992 Professor Heyes joined Rolls Royce plc working in the Applied Science Laboratory on the development of optical diagnostic techniques for high temperature and reacting flows and on the gas dynamics of power station circuit breakers.

In 1995 Professor Heyes moved to Imperial College London joining the Department of Mechanical Engineering as a lecturer in Thermofluids. He left Imperial in July 2013 as Reader in Heat Transfer, Deputy Director of the Energy Futures Laboratory and Director of the Sustainable Energy Futures masters programme.

Professor Heyes is a chartered engineer, a fellow of the Institute of Mechanical Engineers and a fellow of the Higher Education Academy.

Research activities

Overview

My research interests lie in the areas of experimental thermofluids, sustainable/renewable energy and energy efficiency in commercial and industrial processes and the built environment.

Experimental Thermofluids

In the most general sense my research and that of my students can be categorised as experimental thermofluids. In my view, despite the obvious value and importance of simulation, there is nothing more convincing than nor any real substitute for accurate and precise experimental data. My experience in the field is varied but there are two recurring themes. The first is the development and application of non-intrusive, optical, flow diganostic techniques. The second is the study of extreme flows. I and my students have, for example, studied supersonic flows, the transient flow in power station circuit brakers and flows and heat transfer in gas turbine combustors and the hot sections of the turbine that lie downstream of them.

The research has tended to be very applied in nature and one of the main research activities is a good example. Because of a desire to study and develop cooling strategies for gas turbine combustion liners, I started a project experimenting with the phosphor thermometry technique which can give accurate surface temperature data at very high termperatures and in the presence of combustion. This work, conducted by Dr Jorg Feist, lead to the invention of the thermal barrier sensor coating. Various embodiments of these coatings have been studied that allow temperature, heat flux and coating degredation to be measured. Along the way, the coating and instrumentation have changed from an experimental technique to engine sensor and a spin-out company, Southside Thermal Sciences has been set up to commercialise it.
