The system has four vertical blades connected to the horizontal disk. Each blade has two speeds, one around a disk and second local rational along its axis. The method is finite volume CFD code (Fluent v14) with RNG k- turbulence model. For the purposes of this research, a VSP with 4 blades is analyzed at various operating conditions. Hydrodynamic characteristic parameters including moment, thrust and efficiency are presented as functions of advance velocity coefficients at three different pitch rations. http://pubs.sciepub.com/marine/2/3/3/marine-2-3-3.pdf Voith Schneider Propeller CFD RNG turbulence model hydrodynamic performance
