一、前言以往测量一定流动传热条件下的传热表面温度和热流束,一般都使用热电偶、电阻温度计等测温元件。但是用这些方法,当在传热表面安装检测端时,由于检测端外廓与可衡量交界层厚度和气泡大小等的传热过程的特性上的优点比较,相形之下尺寸较大,故而成为传热面的热流紊乱的原因。并且, First, the foreword In the past to measure the heat transfer under certain conditions of heat transfer surface temperature and heat flux, generally use thermocouple, resistance thermometer and other temperature components. However, with these methods, when the detection end is mounted on the heat transfer surface, the size is larger due to the comparison of the characteristics of the heat transfer process at the detection end with measurable boundary layer thickness and bubble size, Heat flow surface heat disorder disorder causes. and,
