Prediction of suppression of vortex shedding from bluff bodies by means of control jets. The group pursues applied and fundamental research into several areas of Computational Fluid Dynamics. Prediction of the environmental forces on full-scale offshore structures Diesel fuel injection system modelling Prediction of vortex shedding from bluff bodies immersed in laminar and turbulent streams and of means for their control. Up Prediction of vortex shedding from bluff bodies immersed in laminar and turbulent streams and of means for their control. Various numerical methodologies have been developed for this purpose, and efforts continue to be focused on finding better ways to represent the physics of two-phase flow motion.
Work also continues on modelling turbulent diffusion processes and spray wall interactions.
The computational work is supported by an extensive programme of experimental investigations wherein flow visualisation and Phase Doppler Anemometry techniques are used to provide the necessary data to validate the computations. Examples of this work can be seen in pic.1 and pic.2 . An example of experimental visualisation of the spray inside the piston bowl of a diesel engine can be seen in pic.3 . Up Cavitation modelling The ability to mathematically model the process of cavitation is essential to improving the design of diesel injection systems, pumps and propellers. An example of the computational work undertaken to simulate the detailed bubble dynamics can be seen here .
