... experiments show that the forces on propellers can be differed by 20% in the nominal inflow and effective inflow. This difference is due to coupling of the propeller to the vorticity in the incoming flow namely, the ship wake. The simulation of effective wake has been done by various numerical methods...

... performances. SHI developed a novel ESD named SAVER Fin(SAmsung Vibration and Energy Reduction Fin), which is a simple fin-shaped appendage attached on the stern bilge area. It produces a series of strong vortical streams, which accelerates retarded flow near stern region to make inflow of the propeller more...

... Efficiency Design Index) as well as cost controlling. Based on the mechanism of contra-rotating propeller, a well designed propeller shaft bracket can generate positive circumferential inflow for aft propeller, which results in a reduction of the overall rotational energy losses in the wake.

... on two- dimensional direction dependent drag, lift and torsional load coefficients. The BEM method described in Merz (2008) is used for calculation of the local wind field around the rotor blades. The applied BEM code includes dynamic inflow, i.e. a time delay on changes of induced velocity related...

... to satisfy the force-free condition on the propeller and turbine wake surfaces. It was found that the position of the trailing wake is very important in predicting the performance of propellers or turbines in steady or unsteady flow. The effects of a non-linear interaction between uniform inflow...
