Abstract
This paper is presented the interaction between propeller and rudder at different operating conditions by using ANSYS-Fluent software. A moving reference frame (MRF) method is applied and the flow equations are solved using Reynolds-Averaged Navier-Stokes (RANS) method and the K-Ï SST turbulent model. The propeller is selected VP1304 and rudder is spade type with NACA0015 section. Hydrodynamic characteristics of the propeller with and without rudder, effect of rudder on the propeller performance, rudder lift and drag, pressure and velocity contour are presented discussed. The results show that the rudder effect on the propeller is small while the propeller on the lift and drag of the rudder may be significant.
Highlights
Propeller and rudder are located behind the ship where the flow into the propeller is non-uniform and unsteady
Ghassemi et al carried out comprehensively on different marine propulsors using computational fluid dynamics and boundary element method (CFD and BEM). They investigated on the hydrodynamic characteristics of the propeller-rudder system (PRS) and AZIPOD [12,13,14]
The present numerical results of the propeller characteristics are well agreed with the experimental data at high at low advance coefficients
Summary
Propeller and rudder are located behind the ship where the flow into the propeller is non-uniform and unsteady. Ghassemi et al carried out comprehensively on different marine propulsors using computational fluid dynamics and boundary element method (CFD and BEM). They investigated on the hydrodynamic characteristics of the propeller-rudder system (PRS) and AZIPOD [12,13,14]. They prepared a comprehensive HPSOP code for hydrodynamic multidisciplinary optimization of a ship and its propeller [15,16,17,18]. The numerical results of the propeller and rudder interactions are presented.
