AbstractIn January 2004, Memorial University of Newfoundland (MUN) purchased a Particle Image Velocimetry (PIV) system for making flow measurements in a towing tank. The system was innovative since the expensive laser and CCD cameras were placed in air, above the water surface and images of the seed particles were obtained by observing the underwater flow through boroscopes. This paper describes the PIV system and presents some preliminary results of flow measurements. The first set of results was obtained from experiments with a small propeller in stationary flow. The second set of results was obtained from measurements of the downstream wake of an escort tug with a yaw angle. The third set of results shows the flow measurement of vortex induced vibration for a flexible riser model.
