Abstract

The effect of free surface on the flow around a rotating propeller and the open water characteristics are studied by varying the propeller immersion depth to investigate the applicability of the new body-force method. A simplified quasi-steady blade element theory (BET) with the infinite-bladed propeller model is coupled with the Reynolds averaged Navier-Stokes (RANS) code CFDSHIP-IOWA to calculate the flow around the propeller near the free surface. Propeller open-water characteristics are simulated in still water for different immersion depths for the Methodical-AU type fixed-pitch propeller. The results show that the wake structure is heavily affected by the free surface. The propeller open characteristics are compared with experiment.
