Data from the pressure measurement of a pitching airfoil NACA643418

The present experimental work is motivated by the need for additional insight into the vortex-induced vibrations (VIV) of airfoils at high angle of attack from an aerodynamic perspective. Airfoil NACA643418 is set to periodic pitching motion. This experimental dataset temporarily contains surface pressure measurements of a pitching airfoil with a mean angle of attack set at 170 degrees, pitching frequency of 2 Hz, and pitching amplitude of 1o degrees.

本实验研究的初衷在于，从空气动力学视角深入探究大攻角翼型涡激振动（Vortex-Induced Vibrations, VIV）的相关特性。本次实验选用NACA643418翼型，并令其做周期性俯仰运动。本实验数据集暂包含该俯仰翼型的表面压力测量数据，其平均攻角设置为170度，俯仰频率为2赫兹，俯仰幅值为1度。
