Development and assessment of CFD methods to calculate propeller and hull impact on the rudder inflow for a twin-screw ship

Andrea Franceschi et al.

Summary: This study investigates the main interaction effect of hull and propeller on the rudder inflow in a conventional manoeuvring simulator using a simple but robust approach. The modular/MMG based method describes the hull, rudders, and propellers with separate mathematical models to account for interaction phenomena. Numerical models developed in OpenFOAM for propeller-rudder interaction and two different approaches for hull-rudder interaction show improved accuracy compared to a calibrated semi-empirical model.

Assessment of the Manoeuvrability Characteristics of a Twin Shaft Naval Vessel Using an Open-Source CFD Code

Andrea Franceschi et al.

Summary: This study evaluated the prediction quality of a twin-shaft naval vessel's manoeuvre using CFD hydrodynamic coefficients, demonstrating that the application of these coefficients provided a good estimate of the main IMO manoeuvres. The DTMB 5415M frigate was used as a test case, which has been investigated in various research studies and international benchmark workshops.
