Abstract

The calibration coefficients of two commercial anemometers equipped with different rotors were studied. The rotor cups had the same conical shape, while the size and distance to the rotation axis varied. The analysis was based on the 2-cup positions analytical model, derived using perturbation methods to include second-order effects such as pressure distribution along the rotating cups and friction. The comparison with the experimental data indicates a nonuniform distribution of aerodynamic forces on the rotating cups, with higher forces closer to the rotating axis. The 2-cup analytical model is proven to be accurate enough to study the effect of complex forces on cup anemometer performance.

摘要

研究了配备不同转子的两种商用风速仪的校准系数。转子杯具有相同的圆锥形，而其尺寸和到旋转轴的距离有所不同。分析基于双杯位置分析模型，该模型是使用微扰方法推导得出的，以纳入二阶效应，如沿旋转杯的压力分布和摩擦力。与实验数据的比较表明，旋转杯上的气动力分布不均匀，靠近旋转轴处的力更大。事实证明，双杯分析模型足够精确，能够研究复杂力对杯式风速仪性能的影响。
