A new primary breakup model of fuel spray with multi-component is proposed by considering the turbulent energy induced by the cavitation bubble. The model proposed here deals with bubble behavior inside nozzle, namely, the process of the growth, the shrinkage and the collapse processes are taken into account by applying Rayleigh-Plesset equation. The resultant energy contributes to the enhancement of initial perturbations on the spray surface and the perturbations grow under the action of aerodynamic force. The model proposed is implemented into KIVA-3V code in order to validate the effect of energy generated by the cavitation on the primary breakup of the discharging jet.
