The objective of the present work is to investigate numerically the 3D flow within diesel injector-like geometry using a cavitation model implemented in a commercial CFD code. A comprehensive study of various numerical parameters is performed which can subsequently be used to simulate cavitation under realistic diesel engine conditions.Numerical predictions were performed on a throttle channel at different operating conditions, with and without cavitation , and compared to available experimental measurements. Overall , it was found that the cavitation model was able to predict the onset of cavitation . Satisfactory agreement was found in both the injection rate and the occurence of chocked flow conditions when compared with experiments.
