A Study of Practical Supercavitating Propeller
Journal of the Society of Naval Architects of Japan, 2004 This paper describes the design and performance of practical supercavitating propellers (SCPs).Prototypes of SCPs were designed using two design methods, in order to check both geometric forms. One was developed by SSPA, and the other was based on the theoretical research having been advanced in recent years.

Numerical study of sweep angle effects of the control fin in supercavitating flow
Engineering Applications of Computational Fluid MechanicsIn this study, we numerically investigated the effects of sweep angle variations (Λ = 0°, 30°, 60°) of the control fin in supercavitating flow. Simulations were conducted using an unsteady Reynolds-averaged Navier-Stokes (URANS) approach coupled with the
