Project overview
The main thrust of the proposal concerns experimental studies of the generation and control of flow noise emissions that limit the social acceptability of new cars, heavy trucks and industrial plant. High quality product design is tending rapidly towards digital processing, thus placing more effort in the virtual world rather than the physical. However, current predictive software does not include flow noise. This is largely due to the limited ability of current software to simulate all the essential details of the associated unsteady or turbulent fluid motion. Detailed acoustic and velocity field measurements will be made with a sequence of generic geometries to locate and quantify the flow noise sources in relation to the associated system geometry and fluid motion. This data will be processed to produce new flow noise predictive models to extend existing noise emission predictive software used for system design optimisation and control of noise. Resulting performance improvements accompanied by more rapid prototype development cycles will be reflected in the manufacture of high quality low cost products with increased market opportunities.
