Services for Business

At the CFD Centre at the University of Leeds, we have experts available to assist industry and executive bodies across virtually all imaginable scenarios where CFD can make a contribution to research, design, evaluation and characterisation, or problem solving and testing of alternative approaches to engineering situations.

We are able to operate in all aspects of land, sea and air activities, across all length scales from nanoscale to bulk unit operations, from energy flows to particulate precipitations. One particular example is the analysis of the Concorde crash below, where CFD analysis was able to show how the design of undercarriage stowage areas could be modified to improve safety.

Other fluid flow and heat transfer problems

We have an excellent knowledge of a number of commercial CFD software packages as well as developing user-friendly in-house codes. Work on fluid flow and heat and mass transfer has implications in many areas of industries including aerodynamics, multiphase flow and conjugate heat transfer.

Modelling flow past a V-bottom speed boat.

The CFD centre was asked to undertake some consultancy work on an exciting project involving modelling flow past a power boat. The aim of the research was to improve the aerodynamic design of the boat such that the new design would be able to break the V-bottom power boat world record. While CFD simulations are now essential in Formula 1 car design they remain unused in this application to speed boat development. However, it is thought that the potential of CFD in helping build faster, quieter and better handling boats will soon be realised.

Concorde accident investigations

A fatal accident in July 2000 involving an Air France Concorde near the Charles De

 Gaulle Airport in Paris led to the temporary grounding of the entire fleet of these supersonic passenger planes. As part of the investigation to explain the accident, we were asked to look into the reason why the fire stabilized on the wing once it started. A CFD model has been developed to understand the flow characteristics of the leaking fuel that gave rise to the observed flame formation. Several simulations were performed using an estimated takeoff speed and a range of attack angles that matched amateur photos of the incident. The CFD study, plus other recent studies on how to improve fuel tanks for the Concorde fleet, led to modifications to prevent a similar incident from happening again.
