Accurate Capture of Propeller-Rudder Interaction using a Coupled Blade Element Momentum-RANS Approach

Abstract This paper compares experimental results with numerical simulations using three different body-force propeller models. The results demonstrate that as long as the radial variation of axial and tangential momentum generated by the propeller are included, the influence of the unsteady propeller flow can be removed and calculations with a steady propeller model can be performed for the evaluation of the influence of the propeller on the rudder.
