Dr Rendall is a member of fluid and aerodynamics research group, working in the field of numerical simulation (CFD - computational fluid dynamics).

Dr Rendall's research is focussed on unsteady CFD (with moving objects), optimisation and interdisciplinary numerical modeling.

• The goal of work on unsteady CFD is to advance current methods to the point where it will be possible to easily model flows around moving, sliding or rotating objects, so that problems such as pistons, valves and propellers may be dealt with simply. Eventually, this will lead to full-flight aerodynamic simulation of aircraft.
• He is also collaborating on work aimed at optimising aerodynamic designs computationally, which will give designers greater insight into how to improve aircraft efficiency in the future.
• Interdisciplinary work is across a range of themes, including composites, aerial refuelling and icing simulation
