摘要

针对太阳辐射加热导致的误差显著限制了温度测量的准确度的问题

提出了基于流体动力学的太阳辐射误差的修正方法——数值分析法。建立从地面到32 km高空不同气压条件下珠状热敏电阻器探空温度传感器的误差热分析模型

通过计算流体动力学对其进行太阳辐射误差数值模拟分析。着重研究了太阳辐射方向、传感器表面涂层反射率、传感器尺寸等物理参数对太阳辐射误差的影响。研究结果表明:太阳辐射引起的温度测量误差随海拔高度的上升呈现非线性单调递增的变化趋势。当太阳辐射方向垂直于传感器正面时误差最大

增大传感器表面涂层反射率、减小传感器尺寸都能有效降低太阳辐射误差。

Abstract

Aiming at problem that error of sounding temperature sensor induced by solar radiation seriously affects the accuracy of temperature measurement

present a novel numerical analysis method based on computational fluid dynamics to correct solar radiation error. The error thermal analysis model of sounding temperature sensor with bead thermistor is established from ground to 32 km altitude with different air pressures

and computational fluid dynamics is employed for numerical simulation analysis of solar radiation error. The solar radiation errors are reported in different physical parameters such as the direction of solar radiation

the surface coating reflectivity of sensor and the size of sensor. The results show that the solar radiation errors present a non-linear monotone increasing trend with the rise of altitude. Among the errors caused by solar radiation

the error is biggest in the direction perpendicular to the front of the sensor. The simulation results also indicate that the solar radiation error can be significantly reduced by improving the surface coating reflectivity of sensor

or reducing the size of sensor.
