Thermal conductivity of catalyst layer of polymer electrolyte membrane fuel cells: Part 1 – Experimental study

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 ...

Investigation into the Influence of Fused Deposition Modeling (FDM) Process Parameters on the Thermal Properties of 3D-Printed Parts

This paper attempts to expand the data for the thermal properties of materials used in 3D printing, which was considered limited before. This new data set may be useful in accelerating new developments and designs of heat exchangers. The effect of layer height and width are accounted for in the presented measurements. It is shown from varying these dimensions that as the layer height and width increase the Author(s): ,

Thermal properties of asphalt concrete: A numerical and experimental study

Asphalt concrete must often endure a range of different weather conditions, and its thermal conductivity is affected by these changes. Using the Finite Element Method (FEM), this paper develops a two-dimensional numerical model used to study and predict environmental effects and validates it through experimental results from the transient plane source method. It was also shown that an increase in the ratio of the TPS sensor size to the maximum ...

Characterization of temperature profiles in skin and transdermal delivery system when exposed to temperature gradients in vivo and in vitro

Elevated temperatures enhance the drug delivering ability of many transdermal delivery systems (TDS). This paper uses an in vivo method to examine the effects of heightened temperature on TDS, which can be applied to in vitro research. A Thermal Constants Analyzer measured the thermal conductivity and thermal resistivity of the TDS using the transient plane source (TPS) method at 40°C. The experimental in vivo thermal resistivity results for skin were ...

Nano insulation materials: synthesis and life cycle assessment

Buildings are responsible for a large portion of the world’s energy use, so there is a high global demand for cost-efficient thermal insulating materials. In this paper, the thermal properties of hollow silica nanosphere nano insulation materials (HSNS NIMs) were examined to test their potential as superinsulating materials. A thermal constants analyzer measured the thermal conductivity of the NIMs using the transient plane source (TPS) method. Results showed that ...
