ABSTRACT

The shapes of the slender steady axisymmetric ventilated cavities are calculated for up- and downward directions of water flow at different values of the Froude number and radii of the cylindrical hulls located inside the cavity. The ventilation is shown to increase the dimensions of the cavities produced after the conical cavitator and to decrease the length of base cavities. If the direction of water flow at infinity is opposite to that of the gravity, the injection rate cannot exceed some critical value for conical cavitators and cannot be lower than some critical value for base cavities.

KEY WORDS
