Resum
The present study deals with the numerical study of the micro-jet velocity and the cavitation - erosion on an axisymmetric nozzle, which presents high ow unsteadiness and aggressiveness. The proposed model is based on energy conservation for the micro-jet velocity prediction, and assumes the potential and kinetic energies, at the start and at the end of the cavity collapse, respectively. The mass transport between liquid and vapor is closely related to Rayleigh Plesset's equation. Results have b...
