Research Group: 
Applied Aerodynamics


Research Interests:
Two-phase flows (sprays), fuel injector aerodynamics, aero-acoustic effects on fuel injectors.


Degree in Aeronautical Engineering from Loughborough University (1993). Joined the Rolls-Royce UTC in Combustion Aerodynamics at Loughborough shortly after graduation.


Design and operation of bespoke isothermal test facilities for experimental investigation of aerodynamics and fluid-dynamics of fuel injectors, at ambient or elevated pressures.

Optical measurements of single and two-phase flows including investigation of aero-acoustic interactions. Techniques include PDA, LDA and imaging with fluorescent tracers, in addition to the development of advanced experimental techniques such as dynamic planar film thickness measurement.

Unsteady measurements utilising Kulite fast response pressure transducers (in addition to the above techniques) examining effects of instabilities on the fuel injector flows.

Other recent work includes acoustic damping using resonators, compressor outlet guide vane flows and their integrated design with combustor (pre-)diffusers or compressor interconnecting (s-shape) ducts.

Development of PC based data acquisition and control systems using LabVIEW, including communications with primary and ancillary equipment. Other measurement techniques include miniature five-hole pressure probes and hot wire anemometry.
