... This paper presents the analyses of the hydrodynamic performance for a marine water-jet propulsor and a rocket engine turbo pump inducer by using a potential flow solver based on a low order panel method. The steady and unsteady fully-wetted and cavitating simulations for the water-jet rotor...

..., the single rotor/stator concept was optimized to maximize efficiency while matching a given design point. The resulting design is predicted to have much improved cavitation performance compared with a design accomplished with older techniques. Other advantages are reduced weight, shorter length, and lower...
