Outline of main research interests
Experimental and computational study of the internal flows within modern gas turbines. Fundamentally this includes diffusing flows, boundary layer separation, wake mixing, secondary flows, and the effects of swirl, curvature and pressure gradients. This extends to more applied systems such as low emission combustor architectures, the compressor/combustor interface, integrated outlet guide vane design, advanced pre-diffuser development, fuel injector design, the combustor/turbine interface and transition duct aerodynamics.
