摘要 本文利用电容层析成像(ECT)的方法,对通道型多孔介质内单/双火焰分布情况以及泡沫型多孔介质内火焰分布进行可视化测量。在介绍和分析多种成像方法的适应性和局限性的基础上,针对被测对象的性质和特点采用了适当的成像方法及其合适的满标定物质,得到了清晰的火焰图像。测量结果显示了ECT可以较为准确地判断多孔介质内火焰的位置、大小以及脉动情况。其成果为多孔介质燃烧领域提供了新的研究方法和测量手段。本文最后指明了测量过程中存在的问题以及今后的发展方向。 Electrical capacitance tomography (ECT) is applied in non-intrusive visualization of the flame (s) distribution in different porous media. Suitable calibration method is sought and adequate image reconstruction algorithm is applied for such a task. ECT results clearly show the shape, size and motion of flame (s) in porous media, which is a breakthrough in the visualization of combustion process in porous media. Future directions for improvement are also suggested.
