摘要

双加热湿度传感器可实现大气湿度连续探测。液滴、冰晶等水凝物覆盖在双加热湿度传感器表面

容易导致其测量精度和响应速度降低。为了提高测量精度和响应速度

有必要对双加热湿度传感器进行除湿处理。采用Pro/E建立4种尺寸的双加热湿度传感器三维模型;利用ICEM CFD中模块化的方法对模型进行分网

得到了较高的网格质量

降低了计算时间

提高了计算精度;利用Fluent稳态分析模拟出2只湿度传感器不同间距下的相互影响情况

瞬态分析模拟出升温时间和降温时间特性。根据仿真结果

提出高空和低空2种模式加热策略。

Abstract

Twin heated humidity sensor can achieve continuous detection of atmospheric humidity.Hydrometeors like liquid

ice crystals will cover on the surface of twin heated humidity sensor

which makes it easy to lower measuring precision and response speed.In order to improve measuring precision and response speed

it is necessary to dry the twin heated humidity sensor.Software like Pro /E is used to build 3D model of four kinds of size of twin heated humidity sensor;modular method of ICEM CFD is used to mesh heated twin humidity sensor by which a higher quality of mesh is obtained

calculation time is reduced and calculation precision is improved;Fluent method is used

steady-state analysis has been implemented to simulate interaction of the twin humidity sensors with different spacing

transient analysis has been carried out to simulate charactenstics of heating and cooling time.Two different heating strategies

high-altitude and low-altitude modes

are proposed based on simulation results.
