The phenomenon of cavitation occurs in high-pressure fuel injectors, extending from their starting point around the nozzle orifice inlet to the exit, where it influences the formation of the emerging spray. The improved spray development is believed to lead to a more complete combustion process, lower fuel consumption, and reduced exhaust gas and particulate emissions.
The objective of CANNEx is to deliver new perspectives on cavitation phenomenon to the scientific community, in order to enhance our current knowledge and our ability to control this phenomenon in the context of high injection-pressure applications.
Computation and experimental results will be confronted to each other to identify:
- the relations between cavitation and spray formation,
- the involved mechanisms. Application to innovative nozzle design is also under the scope of the project as far as these designs will be achievable for transparent nozzles.
