Drag force as a function of cross section, velocity and angle of attack.

An aluminium cross-section approximately 1 m in length was held between 2 flat plates connected to a movable carriage in a wave basin. Under still water conditions, the cross section was moved through the wave basin. Data were collected from an array of load cells in 6 DoF. This process was repeated for four cross sections, each at 4 angles of attack and 7 velocities. These data can be used for all research scientists and engineers working in the fields of fluid mechanics and hydraulics. The data may be used specifically for the validation of numerical models

本实验将一根长度约1米的铝合金截面构件固定于波浪水池内两块与可移动台车相连的平板之间。在静水环境下，驱动该截面构件沿波浪水池行进，通过六自由度（6 Degrees of Freedom，6 DoF）阵列式测力传感器采集实验数据。针对4种不同截面构件重复上述实验流程，每种构件分别在4个攻角工况与7个运动速度工况下开展测试。本数据集可供流体力学与水力学领域的全体科研人员及工程师使用，可专门用于数值模型的验证工作。
