摘要

Abstract: The wake of a ship is a region of highly turbulent flow. The wake characteristics are dependent on hull shape and propeller performance. In order to progress hull deign and maximize vessel performance detailed measurements of the flow are required in this difficult region. The present paper describes experiments in which PIV measurements of the turbulent flow in the wake of a model ship were made using a pulsed Nd:YAG laser illumination system which was computer controlled. The experiments were conducted in a 25 m towing tank with a 1:97 model destroyer. The laser beam entered the tank via a periscope. Observations were made using a second periscope viewing arrangement. During the experiment the YAG laser was fully controlled by computer to optimize the output and to control the distribution of energy between pulses. The camera operation was also controlled by computer. A description is given of the experimental arrangements including the control system used with the laser. The optical viewing arrangements are described as is the method of image analysis used. Example velocity measurements are presented.!9
