Summary on Grant Application Form |

The proposed research, which would be performed at University College London, is an experimental investigation of the near-nozzle characteristics of fuel sprays issuing from pressure-swirl atomizers of the type typically used in direct-injection gasoline engines. The research is motivated by the large discrepencies that exist between the spray break-up characteristics predicted by existing numerical models and the fuel spray break-up characteristics that are observed experimentally. These discrepencies suggest that the physical processes governing the break-up of the spray are not yet fully understood. The proposed research aims to aquire detailed photgraphic data (with a high-speed camera system) on the spray break-up subject to a wide range of ambient injection conditions and several different fuel compositions. It is intended that the experimental work be carried out in two purpose built test rigs that would allow the independent control of ambient pressure, temperature and air flow. Mathematical models describing the observed break-up phenomena would be developed from the experimental results for future incorporation in multi-dimensional computational fluid dynamics (CFD) codes.
