In this study, a methodology for modeling cavitation phenomena with considering the turbulence effect has been applied to a specific geometry and results are compared with experimental results. Results show that increasing the flow velocity inside the nozzle will increase the cavitation regime inside the hole. Study on velocity field near to the hole inlet corner shows that the results of the simulation are conforming the experimental results and theoretical estimations. The simplicity and accuracy of this methodology make a valuable structure for simulation of the cavitation inside the diesel injectors. Also results for outlet section can be used for simulation of the fuel spray inside the engine.
