WIND TUNNEL STUDIES OF A SHIP MODEL USING VORTEX GENERATORS TO IMPROVE WAKE VELOCITIES

During trials of a 13,000 ton displacement cargo ship severe vibration occurred which was attributed to the propeller working in a strongly non-uniform velocity field. This report gives the results of a series of wind tunnel experiments performed on a reflex model fitted with vortex generators which substantially improved the wake velocity distribution. It was recommended that these generators be geometrically scaled and fitted to the ship in order to improve the wake velocity distribution and reduce the vibration of the ship to an acceptable level.
