Research
Research interests
- His fluid dynamics expertise lies in the synthesis of analytical, experimental and computational methods for a diverse range of applications. Examples of such work are in the development of a patented integrated tidal energy generator (winner of The Engineers’ Energy Sector Innovation award 2008), supervision of the students who designed Amy Williams’ Gold medal winning bob skeleton sled (winner of The Engineer’s Sport Technology Innovation award in 2010) and with continued support for Gold medal success in 2014 and 2018, academic supervisor for the Delphin Autonomous underwater vehicle (winner of the SAUC-E competition in 2007).
- He has acted as a consultant to diverse organisations including NOC, Speedo, Shell Shipping, BAEsystems, Rolls Royce, dstl, QinetiQ, and WS Atkins.
- Expertise: Future Fuels for Shipping; Maritime Robotics and Autonomy; Rudder, hydrofoil, and control surface design; Unsteady race simulation for kayak, rowing and sailing; Hull-propeller-rudder interaction; Ship added resistance and manoeuvring in waves; Underwater noise prediction using CFD; Experimental techniques for use of wave/tow tank testing; Tidal turbines, wave energy and offshore wind turbine design; Wind turbine array power prediction; Hydrogen fuel cells for hybrid ship propulsion; Hydrodynamics of swimming assessment by pool based test techniques and using CFD.
- PhD Supervision: I lead a team of researchers and PhD students with funding of from a wide range of sources including EPSRC, dstl, EU, UK Sport, and industry.

Optimized athlete body sensor networks for simulation-based performance analysis
We have developed a system of wearable sensors that gather information about the movement of athletes so that we can then simulate what their muscles are doing, their aerodynamic drag, etc. This will allow us to optimize the athlete's technique in much the same way as an aircraft's shape is optimized.
Cavitation erosion-corrosion of ship propeller materials
Cavitation erosion-corrosion phenomenon is inevitable in marine propulsion system and has adverse effects on the life and functioning of the propellers. The intensity of the cavitation wear and the exact location of its occurrence have been found to be difficult to predict.The main aim of this PhD project is to identify cavitation wear-corrosion mechanism of marine materials used in propellers and rudders in order to characterize the materials based on their behaviour to cavitation erosion simulated by a vibratory probe device. Several tests will be conducted, with and without cavitation protection, using both direct and indirect methods of cavitation erosion tests along with incorporation of Computational Fluid Dynamics (CFD) modelling of the experiment.This research is sponsored by the university research groups National Centre of Advanced Tribology at Southampton (nCATS) and Fluid-Structure Interaction (FSI), along with Lloyd’s Register.
