Artificial cavitation, or ventilation, is produced by releasing gas into liquid flow. One objective of creating such a multiphase flow is to reduce frictional and sometimes wave resistance of a marine vehicle completely or partially immersed in the water. In this paper, flows around surface ships moving along the water-air boundary are considered. It is favorable to achieve a negative cavitation number in the developed cavitating flow under the vessel's bottom in order to generate additional lift. Cavities formed in the flow have limiting parameters that are affected by propulsive and lifting devices. Methods for calculating these influences and results of a parametric study are reported.
