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
