Authors have developed a spray model for multicomponent fuel and reported the successful model which represents batch-distillation in multicomponent fuel by employing chemical thermo dynamics analysis including liquid-vapor equilibrium. However, the model considers the aerodynamic interaction as a breakup force by employing Taylor Analogy Breakup but ignored internal nozzle flow characteristics in spite of their importance. Nozzle flow is one of the major mechanisms for atomization of liquid jet. Therefore, this paper deals with a new breakup model for multicomponent fuel spray. The model takes account of the energy induced by cavitation bubble collapse or shrinkage. In addition, the model is implemented into KIVA-3V code in order to validate the effect of energy generated by cavitation on the primary breakup of the discharging jet.
