“…However, there is an inherent limitation with this type of cavitator configuration -it neglects the effects of the cavitator shape or the presence of the mounting strut, both of which have been shown to noticeably affect the cavity behaviors [7][8][9], especially the supercavity formation process [10]. Recently, Shao et al [11] studied the ventilation demands for a forward-facing model (FFM) with a variety of cavitator geometries (cone, disk, and nonaxisymmetric) to consider both the cavitator shape and the mounting strut effects. They have found out that the cone type cavitator required the least ventilation flow to form and sustain a cavity.…”
