Abstract:Acquiring the thermal conductivity in high temperature accurately has important implications for using insulation materials. In this paper, the principle of the measurement of the transient hot plane method is introduced. For rising the operating temperature, the plane heat source with film is changed to no film one. So the measurement errors caused by film can be eliminated. Because of the low thermal conductivity of insulation materials and that the sample should be heated up to a high temperature, the prehe… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
