Analysis of the propeller-hull interaction by LDV phase sampling techniques


In the present paper the results of the wake survey in two stern sections of a twin screw ship model, located just upstream the propeller disk and behind the directional rudder, are presented. Experiments have been performed in a large towing tank by using a Laser Doppler Velocimeter and phase sampling techniques, in order to analyse wake evolution with the propeller angular position. The main features of the propeller installation are highlighted as well as the strong and complex interaction of the propeller with the hull wake, especially in the brackets region and downstream the directional rudder.
