| Abstract: | This paper calculates the hub hydrodynamic performance using overall structured grid by CFD method. The simulation method is first validated, and then influence of three typical different hub shapes on their open water characteristics, section pressure distribution and cavitation are investigated. The comparison results show that arc shaped hub has the smallest resistance and highest efficiency. The hub mainly influences the blade root flow. The cylinder shaped hub has the lowest pressure near blade root and largest cavitation area. Arc shaped hub has the best cavitation performance. |
