火焰三维温度场重建的研究

An Experimental Study on Visualization of 3-d Temperature Fields in Flames

文章给出了利用面阵CCD进行火焰三维温度场重建的系统结构和基本原理,重点分析了利用外等值线重建火焰三维温度场的新方法,以蜡烛为例,用三个固定位置的CCD摄像机分别聚焦火焰的不同截面,得到三张火焰的侧面图,对该组图像运用火焰的外等值线建立模型,最后给出了三维重建的效果图,并证实了其可行性,为进一步研究火焰三维温度场在工业领域的运用奠定了基础。

In this paper,the use of a array CCD reconstruction of the three-dimensional flame temperature field structure and basic principles,the focus of the use of three-dimensional contours reconstruction flame temperature field of new ways,to candles for example,using three fixed position CCD cameras were focused flame different sections by three flame profile,the group image of the use of flame contour model building,and give the effect of three-dimensional reconstruction plans,and confirmed its feasibility,for further study three- dimensional temperature field in the industrial field laid the foundation for the application.
