With the use of multiple thermal instruments, the thermal conductivity (lambda) of fibrous insulations was measured in the plane direction. In this study, a method was put forth the estimate thermal conductivity. This method assumed that the thermal conductivity of the anisotropic material was equivalent ...
In this paper silica aerogels were synthesized using solvent exchange and surface modification of wet gels from waterglass using IPA/TMCS/n-Hexane solution. The densities, porosities, and specific surface areas were measured. Three different mixing methods were employed to determine their effect on the thermal ...
Thermal conductivity and thermal diffusivity of two poly(methyl methacrylates) were measured using multiple methods; temperature wave analysis, laser flash, transient plane source, transient line-source probe, and heat flux meter. The main reasoning behind this study was to compare results between methods, to ensure repeatability ...
This article delves into the depths of the transient plane source (TPS) method for measuring thermal conductivity. When dealing with insulative materials, thermal conductivity is one of the most important thermal properties, as it directly reflects the R-value – amount of heat-transfer resistance the insulation provides. ...
Barium titanate-based ceramics are most commonly found in electronics as dielectric layers in multilayer ceramic capacitors. Two different forms of Barium titanate-based ceramics were analyzed in this article to determine heat capacities as a function of temperature. The thermal conductivities and thermal diffusivities of these ...
