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.

为了了解船舶在波浪中的推进性能，除了附加阻力外，波浪对螺旋桨平面内伴流分布的影响。详细介绍了用于测量波浪中速度分布的体视PIV系统。通过对系统在拖曳水池中的调试和静水中的初步测量，介绍了相均流场测量系统。研究结果可用于了解和改进推进性能以及CFD验证。
