A chimera Reynolds-Averaged Navier-Stokes (RANS) method was coupled with a propeller analysis program to provide accurate resolution of the propeller-ship interactions. Calculations were performed for a Series-60 ship with the MAU propeller under various operating conditions. In the present interactive coupling approach, the propeller thrust and torque were represented by body-forces and added to the source functions of the RANS code to account for the propeller-induced effects. The propeller analysis program was then used to determine the new propeller blade loading distributions with the propeller inflow provided by the RANS solution. Several interactive coupling between the RANS and propeller analysis programs were performed to capture the propeller-ship interactions under various propeller operations including ahead, backing, crash-astern, and turning conditions.
