The paper describes a new mathematical model for the simulation of unsteady liquid-gas flow in fuel lines. The model primarily focuses on both the accurate prediction of local phase changes and their effects on the unsteady flow in a system such as the propagation of pressure waves. The motivation for this work came from the necessity to predict cavitation in diesel injection systems as well as partial evaporation of volatile (alternative) fuels. The model has been implemented into the AVL program HYDSIM for the simulation of injection systems. The paper shows an application of the model in a diesel injection system and discusses its characteristics at cavitation occurrence.
