Abstract
A RANS-BEM coupling method is described in which the action of the propeller in the RANS solution is modelled using both force and mass density fields. Comparison between the RANS and BEM solution is done at points between the propeller blades and the inflow to the BEM solution is allowed to vary in the axial direction. The difference between RANS and BEM solutions in open water is used to correct the BEM inflow. The method is illustrated using self-propulsion calculations of the BB2 submarine.
