A technique, which couples the lifting surface theory and Reynolds-averaged-Navier-Stokes (RANS) method to analyze the propulsor-hull interaction, was evaluated with towing tank measurements. The experimental database was for an axisymmetric body with a ducted propulsor. This database consisted of propeller thrust coefficient, torque coefficient, and duct force at different advance coefficients. The thrust and torque coefficients were predicted within 10% near design condition. The calculated duct thrust and the thrust deduction coefficients were higher than the measured values all across the operating range. Accounting for the viscous effect on the lifting surfaces is suggested for further study. Evaluation with other databases is strongly recommended.
