Description
Summary:In a previously reported study, wind tunnel experiments were undertaken to investigate the aerodynamic characteristics of hybrid-sails in isolation. Such sails are seen as providing a worthwhile reduction in the delivered power to the propeller and hence the engine generated thrust, with a corresponding reduction in the CO sub(2) production of diesel engine exhaust. In this paper, wind tunnel testing is used to investigate sail-sail interaction effects for two sets of four identical hybrid-sails, and the sail-hull interaction effects for the same two sets of four identical sails in the presence of a bulk carrier hullform. The analysis presented suggests that to build a sail-assisted ship requires an appreciation of the sail-sail and sail-hull interaction effects.
