Abstract
Focusing on the problem of heat-flux measuring in complex and extreme circumstances, a new measuring method based on infrared thermography was proposed. Be superior to traditional radiation heat flow meter which can only measure heat flow at one point, the thermal distribution and heat flow distribution could be gotten easily and accurately in one time with help of a made-to-measure beacon, combined the advantages of contact and non-contact measurement. This study was divided by three parts, theoretical analysis, system construction and numerical simulation. Less than 2% theoretical error was obtained which verifies the accuracy and feasibility of heat-flux measurement technology based on infrared thermography.
