Effects of Rudder and Blade Pitch on Hydrodynamic Performance of Marine Propeller Using CFD

Abstract The use of computational fluid dynamics (CFD) to predict internal and external flows has risen dramatically in the past decade. This research aims commercial software, ANSYS Fluent V.14.5, illustrate effects rudder blade pitch on hydrodynamic performance marine propeller by experimenting with propellers rudders M/V Tan Cang Foundation ship, which designed conditions as follows: diameter 3.65 m; speed 200 rpm; average 2.459 boss ratio 0.1730. Using CFD, characteristic curves some important results showed that maximum efficiency is 0.66 open water 0.689 rudder‒propeller system at advance 0.6. obtained outcomes this are a significant foundation calculate design an innovative kind propulsion for ships high performance.
