Research interest in computational methods for the solution of problems in engineering analysis and design.

MBE FREng PhD DSc FICE CEng FLSW

Professor Hassan research interest is in computational methods for the solution of problems in engineering analysis and design. His main research areas are:

- Unstructured Mesh Generation
- Computational Fluid Dynamics
- Computational Electromagnetics
- Parallel Processing

Professor Oubay Hassan and Professor Ken Morgan, in close partnership with BAE Systems, and Airbus have led the development of the FLITE system that enable the modelling of problems in computational fluid mechanics an computational electromagnetic.

An excellent example, which received significant worldwide publicity, was the use of the developed FLITE system to support the aerodynamic design of THRUST SSC, the car which took the World Land Speed Record beyond the speed of sound in 1997.

Building on his previous success, he has led the team that has developed the CFD technologies that deemed required to ensure a successful aerodynamic design of the new BLOODHOUND Land Speed Record project. The main aim of this project is to use the BLOODHOUND SSC as the platform for provision of high-quality public engagement activities that motivate the next generation to deal with global 21st century challenges.
