WebSummary. A theory for the gas loss in high Froude number flows is constructed on the assumption that the gas loss in ventilated supercavities is caused by entrainment of the gas into the boundary layers on the walls of the cavity which act as moving foils. Webfrom the cavity, but in the case of ventilated cavity, the gas supply rate must meet the rate at which the gas is entrained away. The gas supply necessary to control the cavity …
