用红外热象仪测试气流稳态温度场

Measuring the Temperature Field of Steady Gas Flow with Infrared Thermovision

本文介绍了一种用红外热象仪测试气流稳态温度场的新方法。作为实例，借助于储热板对空—空冷却的叉流板翅式换热器内的温度场进行了测试。取得了既直观又可靠的结果。

A new method for measuring the temperature field of steady gas flow is introduced. By means of a plate with great heat capacity,the temperature field in a crossflow plate-fin heat exchanger is measured.The results are objective and reliable.The error caused by this method is analysed,it indicates that this method is successful.
