This experimental study examines ventilated supercavity formation in a free-surface bounded environment where a body is in motion and the fluid is at rest. The shape of the object is a two-dimensional flat plate, and a straight cavitator is attached to the lower part of the object, and compressed air is blown out behind the cavitator. Two-dimensional supercavitation phenomenon was observed and the associated drag was measured. We found that the drag force was reduced by up to 40%.
