基于辐射图像处理的壁温分布监测实验研究
Experimental research on monitoring the wall temperature distribution by radiation image processing
摘要
Abstract
Combustion monitoring in large industrial furnace can be simplified to a radiation heat transfer problem within the enclosed cavity system,and precise quantification of its boundary radiation characteristic is the basis to carry out follow-up studyon the radiation inverse problem,but the coupled problem of wall radiation and media radiation need to be solved.A Monte Carlo priciple was involved to solve the radiation heat transfer equation in the enclosed cavity,and to decouple the shares of wall radiation and media radiation in the boundary detection information.The influence of temperature distribution and radiation properties on the share of wall radiation were discussed,at last the experiment verifies the feasibility of using the radiation information of boundary detection to retrieve the wall source term.This study will provide a reference to the exploration of physical field detection method of wall surface in industrial furnace.关键词
