摘要
本文在实验室中以蜡烛火焰为研究对象,研究采用辐射图像处理技术重建蜡烛三维温度场。并采用细丝热电偶实测火焰局部温度,对蜡烛火焰三维温度场可视化的结果进行了比较。结果表明,火焰高温区的重建温度是合理的,此方法能够很好地重建单峰、双峰三维温度分布。进一步证实了基于火焰图像处理技术实现三维温度场可视化的可行性。
The 3-D temperature fields of candle flames are investigated in this paper. The 3-D temperature fields are reconstructed using image processing technology. Using thermocouple, the temperatures of candle flames are measured. The measuring result and the reconstructing result are compared , the result is well, especially in the high temperature fields. The single and double apexes temperature fields are reconstructed very well. The method of reconstructing the 3-D flame temperature fields is confirmed further.
