An evolution of a previously proposed anemometer capable of detecting both the magnitude and the direction of the wind on a plane is proposed. The device is based on a recently formalized principle, consisting of combining the differential pressures measured across distinct diameters of a cylinder to estimate the wind velocity and incidence angle. Differently from previous sensors based on the same principle, the proposed anemometers use 3D printing to fabricate the channel structure that calculates the pressure combination in the fluidic domain. Furthermore, commercial sensors with low power consumption are used to read the two pressures that result from the fluidic processing. The whole fabrication procedure requires inexpensive equipment and can be adopted by small enterprises or research laboratories. Two original channel structures, predicted by previous theoretical work but never experimentally validated, are proposed. The results of detailed experiments performed in a wind tunnel are reported.
本文提出了一种对先前提出的风速计的改进，该风速计能够在平面上检测风的大小和方向。该装置基于最近正式确定的原理，即通过组合在圆柱体不同直径上测量的压差来估计风速和入射角。与基于相同原理的先前传感器不同，所提出的风速计使用3D打印来制造在流体域中计算压力组合的通道结构。此外，使用低功耗的商用传感器来读取流体处理产生的两个压力。整个制造过程所需设备成本低廉，小企业或研究实验室均可采用。本文提出了两种先前理论工作预测但从未经过实验验证的原始通道结构。报告了在风洞中进行的详细实验结果。
