Abstract

Spray characteristic and internal flow of a marine diesel nozzle were investigated both numerically and experimentally. In this paper, both investigations were carried out using water instead of fuel. Numerical simulation of nozzle internal flow of the nozzle showed that cavitation can occur inside the nozzle holes.
