本文介绍用红外技术测量微小液滴表面温度的方法。通过对液体辐射特性和光谱透射特性的分析,确定测得的液滴红外辐射是由液滴表面发射的。用比较定标的方法消除了液滴发射率及环境对测试结果的影响。实验结果表明液滴表面温度与液滴内部温度不相同。
This article describes a method of measuring the surface temperature of tiny droplets using infrared technology. Through the analysis of the liquid radiation characteristics and spectral transmission characteristics, it is determined that the measured drop infrared radiation is emitted from the droplet surface. Compared with the calibration method to eliminate the droplet emissivity and the impact of the environment on the test results. Experimental results show that the temperature of the droplet surface is not the same as the droplet internal temperature.
