Using CFD for simulation of ships with different fuel saving rudder-propeller devices

FORCE Technology, Grontmij│Carl Bro and Rolls Royce in Denmark are involved in a joint project
under DCMT (Danish Centre for Maritime Technology). The goal of the project is to test and demonstrate the capabilities of RANS in connection with flow simulations for different rudder and propeller
configurations. Focus is on a complete CFD model for hull, propeller and appendages, which can account for the mutual interaction between the components when
the flow field is calculated. In RANS, propellers can be modeled by body-forces as in , but in the present work the real propeller geometry is modeled using the
same approach as outlined in . In the present work different rudder-propeller configurations are evaluated behind a 180m bulk carrier in order to study how
different configurations influence the ship performance for a given speed at the ships self-propulsion point. In addition to the combined hull-propeller calculation,both propeller and hull are simulated in an open water and a resistance test setup, respectively. In order to check the performance of the CFD model, the calculated results are compared with experimental data
measured in FORCE Technology’s towing tank. All meshing and flow simulation are conducted with Star-CCM+ provided by CD-adapco.
