A STUDY ON IMPROVING HYDRODYNAMICS PERFORMANCES AND POWER EFFICIENCY OF A PROPELLER BY USED CFD

Abstract

In this paper, the authors presents some results of a study on improving hydrodynamic performances and power efficiency of a propeller by theoretical calculations and Computation of Fluid Dynamics (CFD). Base on the hydrodynamic theory of a propeller, an optimal solution on hydrodynamic performances and power efficiency of a propeller is applied. A new kind of propeller is proposed for the ships. The authors present some results of computation and comparison on hydrodynamics performances of the two cases as well as a propeller with and without rudder, and a propeller able to change the blade pitch angle. These are the two important points which propose for the new kind of propeller to apply for the non ballast water ship. The research on improving hydrodynamic performances and power efficiency of propeller is also a study to improve the economics efficiency of the ship in transportation.
