A hybrid numerical method, which is based on a combination of a two-way bubble tracking method and an interface tracking method, is proposed in the present study for the prediction of atomization of liquid jet. Numerical simulation of liquid jet injected through a single hole nozzle in which cloud cavitation takes place is performed to examine the potential of the proposed method. It is confirmed through comparisons between measured and predicted cavitating flows that (1) the combination of bubble and interface tracking methods enables us to examine the effect of cavitation bubbles on liquid jet deformation, and (2) the bubble tracking function of the hybrid method gives reasonable predictions for the distributions of pressure and bubbles within the nozzle, the relation between injection pressure and liquid flow rate, and the behavior of cavitation, though several constitutive models such as cavitation, drag, lift and turbulence models should be based on more sophisticated ones in the future.
