| Research Abstract |
To understand the propulsive performance of ships in waves, the effect of waves on the wake distribution in propeller plane in addition to the added resistance. The stereo PIV system was introduced to measure the velocity distribution in waves in detail. After the adjustment of the system in the towing tank and some preliminary measurement in calm water, the system to measure the phase averaged flow field was introduced. The results can be used for understanding and improvement of propulsive performance and for CFD validation.
