已知振荡翼片可以通过产生反向卡门涡列来产生推力，这可以预期是一种新的高效推进系统。制作了垂荡翼模型，并在循环水槽中进行了试验。利用PIV技术对垂荡翼尾流的形成过程进行了可视化，并利用基于力和力矩检测器的小型六维力传感器测量了垂荡翼的动态推力。我们研究了NACA 0010剖面中的各种条件，如降低的频率和振幅。根据尾流模态和力数据对尾流中的涡型进行了分类。
It is known that an oscillating foil can produce a thrust force through the generation of a reverse Kármán vortex street and this can be expected to be a new highly effective propulsion system. A heaving foil model was made and it was operated within a circulating water channel. The wake formation behind the heaving foil was visualized using PIV method and a dynamic thrust force was measured using a mini 6-axis force sensor based on force and moment detectors. We examined various conditions such as reduced frequency and amplitude in NACA 0010 profile. The vortical patterns in the wake were classified according to the wake mode and force data.
