Numerical Study on the Hydrodynamic performance of single hull model of the Seaplane

Abstract

This paper mainly researched the hydrodynamic performance of seaplane at different conditions. The drag, lift and moment of the single hull model of seaplane at different conditions were compared and analyzed by RANS method. Numerical method in this paper was verified and validated by comparing with experimental results. By analyzing the computed results, the drag increased with the increase of the trim angle, while the moment decreased. When the draft≦30mm, the drag, lift and moment changed little. While the draft >30mm, the drag, lift and moment increased obviously with the increase of draft. The drag, lift and moment increased with the increase of velocity, and increasing obviously when the draft >30mm.
