This paper presents a numerical study of the aerodynamic performances of Flettner rotors on the MARIN Hybrid Transition Coaster (MHTC) at full scale Reynolds numbers. The effects of the interac-tion between the MARIN Hybrid Transition Coaster (MHTC) and its three Flettner rotors are investi-gated. Large interaction effects are found to depend on both the spin ratio and the apparent wind angle. It is therefore concluded that these interactions cannot be omitted. A model based on the thrust identity approach together with a correction for the effective apparent wind angle is proposed to correct the performance of free standing Flettner rotor to the performance of a rotor on the deck of the vessel.
