    The aim of this study is to develop a hydrodynamic cavitation model that is compatible with the results of the experiments and that can be adapted to commercial software. For this reason a hydrodynamic cavitation model that takes into account all of the damping mechanisms using the novel bubble gas pressure law is developed for quasi-one-dimensional bubbly cavitating nozzle flows. In this model the bubbly liquid is assumed to be a twophase homogeneous mixture, the Rayleigh-Plesset equation is employed for bubble dynamics, and bubble nucleation process is neglected. The first order system of equations thus obtained for quasi-one-dimensional cavitating nozzle flows is transformed into an initial value problem for the bubble radius and the pressure coefficient. A numerical code is then written to solve this initial value problem by the adaptive step size RungeKutta-Fehlberg method. Results obtained at the experimental conditions were compared and interpreted with the results of experiments.
