Abstract

Anemorumbograph has been widely utilized in aerospace, aviation, and meteorological monitoring. To achieve the portability and the miniaturization, the design of an anemorumbograph was presented in this research, which was based on fluid dynamics simulation and experimental validation. Firstly, the temperature fields on a plane under different flow conditions were analyzed with FLUENT. Therefore eight NTC thermistors around the central resistance wire were arranged on the sensor surface. Secondly, the responses of the eight NTC thermistors under the winds with various speeds and directions were recorded. Also the effect of the environmental temperature on the thermistors response was illustrated. Then an algorithm based on third-order Fourier series fitting and environmental temperature correction was proposed. Experimental validation with a manufactured sensor PCB with a size of 20 mm in diameter and a power consumption of 0.635 W. Anemorumbograph based on thermal field distribution was also performed through wind tunnel tests. The results demonstrated that the detection range of wind speed was 1–30 m/s ± (0.5 +0.03 v) m/s, and the detection range of wind direction was 0–360° with an accuracy of ± 5°. The sensor has good linearity within ambient temperature range of −10–40 ℃.

基于热场分布的微型高精度验血仪的设计

减震器已广泛应用于航天、航空和气象监测领域。为了实现便携性和小型化，本研究基于流体动力学模拟和实验验证，提出了减震器的设计方案。首先，利用 FLUENT 分析了不同流动条件下平面上的温度场。因此，在传感器表面布置了八个围绕中心电阻丝的 NTC 热敏电阻。其次，记录了八个 NTC 热敏电阻在不同风速和风向下的响应。此外，还说明了环境温度对热敏电阻响应的影响。然后提出了一种基于三阶傅里叶级数拟合和环境温度校正的算法。实验验证了直径为 20 毫米、功耗为 0.635 瓦的传感器印刷电路板。此外，还通过风洞试验进行了基于热场分布的失真记录。结果表明，风速检测范围为 1-30 m/s ± (0.5 +0.03 v) m/s，风向检测范围为 0-360°，精度为 ± 5°。传感器在 -10-40 ℃ 的环境温度范围内线性良好。
