Experimental methodology for characterizing flame emissivity ofsmall scale forest fires using infrared thermography techniques

摘要

An experimental methodology based on thermography techniques has been developedrnand implemented with the aim of finding emissivity values of forest fuel flames. In this paper,rnprevious works by different authors are discussed and theoretical fundamentals of heat transferrnby radiation and of infrared thermography on which experimental method relies are brieflyrndescribed. Then, designed methodology, equipments, devices and experimental tests are detailedrnin depth. Finally, analysis procedure is pointed out and some conclusions from the study of thernresults are announced.
