On Unsteady Flow and Wave Field around the Full Form Ship advancing in waves

为了了解船舶在波浪中的推进性能，除了波浪的附加阻力外，还要研究波浪对螺旋桨面尾迹分布的影响。详细介绍了立体PIV系统在波浪中速度分布的测量。通过对拖曳舱系统的调整和静水中的初步测量，介绍了相平均流场测量系统。研究结果可用于理解和改进推进性能，并可用于CFD验证。

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.
