In this study, an attempt has been made to numerically model the two-phase fluid transient induced cavitation occurring due to the sudden closure of the valve using the Finite Volume Computational Fluid Dynamics (CFD) approach. Also, a one-dimensional numerical model using the Method of Characteristics (MOC) is developed, incorporating the Rayleigh-Plesset equation for modelling bubble dynamics. Results from both models are compared, and it is noted that the CFD excels MOC because it incorporates the radial variation and can better visualize the two-phase fluid transients. But, the MOC method is computationally less expensive compared to CFD.
