In this paper, a new method is proposed for measuring the through plane thermal conductivity of two catalyst layers of different thicknesses by the guarded heat flow meter (GHF) method, and the transient plane source method (TPS). These catalyst layers were made from two catalyst-coated substrates. The effects of pressing, and hot pressing the layers were also studied and shown to have ...
Efficient thermal insulation is becoming increasingly important as people spend more time in buildings. Aerogel blankets are highly porous materials made of polymeric fibers coated with aerogel particles that are used for building insulation. This paper aimed to explore the effect of moisture on the thermal properties of insulating aerogel blankets, because in humid environments, condensation within building insulation heightens thermal conductivity. The thermal constants analyzer TPS measured the thermal ...
Adding thermally conductive materials and consolidating adsorbents in a thermally conductive porous matrix is one way to improve heat transfer in sorption beds. The aim of this study was to develop a model that predicts the effective thermal conductivity of consolidated composite adsorbent containing graphite flakes. A thermal constants analyzer TPS measured the thermal conductivity of consolidate adsorbent graphite flakes using the transient plane source (TPS) method. The results showed ...
This study experiments with the new and improved transient plane source (TPS) method for measuring the thermal conductivity of thin-films. The existing TPS method for measuring thin-films experiences the effect of thermal contact resistance. In this experiment, a thermal constants analyzer is used to investigate the precision and efficacy of the new method. This modified method looks to resolve the issues surrounding contact resistance, with eliminating the need for reference ...
