Wind turbine torque data

The torque data were directly exported from CFD into Excel, and then plotted using Origin. The first column in Excel represents the actual physical time, and the second column represents the instantaneous torque output. The corresponding torque coefficient Ct was calculated using the formula:Ct=T/(0.5*ρ*U2AR)​where T is the instantaneous torque, ρ is the air density, U is the free-stream wind speed, A is the rotor swept area, and R is the rotor radius. The calculated Ct​ values were then imported into Origin for plotting.

本扭矩数据直接从计算流体动力学（CFD）导出至Excel表格，随后借助Origin软件完成绘图。Excel表格的第一列记录实际物理时间，第二列记录瞬时扭矩输出值。采用如下公式计算对应的扭矩系数Ct：
Ct = T/(0.5·ρ·U²·A·R)
其中，T为瞬时扭矩，ρ为空气密度，U为来流风速，A为风轮扫风面积，R为风轮半径。计算得到的Ct值随后被导入Origin软件以进行绘图。
