摘要：

An infrared thermographic technique is developed to obtain the transient solid surface temperature distribution in the neighborhood of an evaporating droplet. This technique is nonintrusive and is not affected by the time response of the measuring device (i.e., thermocouple). The entire surface is monitored at any instant of time, and information on the area influenced by the evaporative cooling process is easily derived. A detailed description of the image processing based data reduction is provided. A water droplet in the range of 10-50-mu-L is deposited on an opaque glasslike material (Macor) that has an initial surface temperature between 100 and 165-degrees-C. The evaporative cooling process is fully documented, and these new findings are contrasted with the published literature to gain a better understanding of the phenomena involved.
