Modelling of Flettner Rotors using CFD

The Wolfson Unit delivered a paper on "Predicted fuel savings for a Flettner Rotor assisted tanker using computational fluid dynamics" at the RINA Wind Propulsion 2019 Conference.

This paper summarised the results of a programme of simulations carried out using Unsteady RANS simulations to model the flow complexities of rotors and the effects of multiple rotors interacting and influence of the ship flow field on rotor performance.
