Three new mass transfer models of cavitation have been studied in two cases of internal flows, a venture and an orifice, numerically. Models were implemented in an open source code for similar condition flows. Volume of gas fraction, in some section of ventury conduit flow, and orifice discharge coefficient are compared to experimental data. Data comparisons shows high precisions in the results of Kunz and Zwart mass transfer models, reached to average less than 5 percent in relative errors while Singhal model shows more deviation, more than 10 percent, from test data. Not any advantage is seems between Kunz and Zwart model in the results of case studies, while Singhal, with more flow parameters accounting, shows more diverted results, therefore more precisions is needed to use this model.
