Cavitation erosion prediction in injectors for diesel engines

CRF has performed an experimental campaign related to the code validation regarding the prediction of cavitation erosion in the A-throttle of the diffusor valve of the injector assembled in multijet diesel engine. The activity was organised as laboratory simulation test on hydraulic test rig. The experimental results were verified using the CFD code FIRE, the results were in good agreement.

AVL used the experimental results of TU Graz, LFDT and LEGI to validate the advanced cavitation model and the erosion model. Compared were the velocity profiles, turbulence quantities, phase distributions and material removal rates. Good agreement between simulations was found.
