Available in PDF, EPUB and Kindle. Book excerpt: The paper discusses some problems related to the guarded hot plate (GHP) and heat flow meter (HFM) apparatus that justify today research efforts and future research programs. For the GHP these include the problem of imbalance detection and its correlation with the metering area definition, the problem of gap width, and the problem of apparatus speed. Also discussed are the specimen-related issues involved in measurements on rigid, highly conductive materials and mass transfer within the specimen during tests.

This book was released on 1991 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The apparent thermal conductivity and thermal resistance of several building insulations were determined at the National Institute of Standards and Technology (NIST) using three apparatus. Reference values were determined with NIST's 1-metre Line-Heat-Source Guarded Hot Plate (GHP). The other two apparatus were heat-flow-meter (HFM) apparatus calibrated with a Standard Reference Material of fibrous-glass board (138 kg/m3). The apparatus -- NIST's 1-metre GHP; the 610 mm HFM; and the 305 mm HFM -- were operated at a mean temperature of 24°C and temperature difference of 22°C across the thickness of the specimen. Measurements of thermal conductivity were determined for individual specimens nominally 25 mm thick, covering a range of thermal conductivity from 0.02 to 0.16 W/(m•K). The thermal resistance of thick specimens (1 to 7 m2•K/W) of cellular plastic, fibrous and loose-fill insulation was also determined. Deviations from reference values of the GHP were calculated for the HFM apparatus. For the 610 mm HFM, the majority of deviations were within ±3% of the GHP. Substantial improvement was achieved by calibrating the 305 mm HFM as a function of thickness; however, deviations ranged from +1.5 to +9.2% from the GHP. The apparatus, test procedure, and analysis of the deviations are described in the paper.

This book was released on 2016 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large-scale guarded hot plate apparatus was designed and constructed for measurement of the thermal conductivity of thick insulation specimens and specimens containing layers and/or complex 3D heat flows (i.e. thermal bridges). The apparatus is capable of accepting specimens measuring 4' (1219mm) by 4' (1219mm) and up to 16” (406mm) thick with good accuracy in measurement. Computer models were developed to estimate heat flow errors important for determining the characteristics and limitations of the apparatus. Other sources of error in measurement were also evaluated. Once constructed, the apparatus was validated against a heat flow meter calibrated to better than 1% using a US National Institute of Standards and Technology (NIST) traceable calibration sample. Good agreement was shown between the heat flow meter and the guarded hot plate;

Available in PDF, EPUB and Kindle. Book excerpt: Thermally Conductive Polymer Composites provides an important introduction to the key principles, methods, and research directions of this emerging thermal management material category. This book introduces thermal conduction, measurement methods, thermal conduction mechanisms, and related theories. It also reviews classification and processing techniques which impact thermal conductivity performance. Thermally conductive composites discussed include intrinsically thermally conductive polymers, thermally conductive fillers, and thermally conductive polymer composites. Furthermore, the interfacial thermal resistance is thoroughly explained including basic concepts, theoretical research, and characterization. Finally, the practical applications of thermally conductive polymer composites are illustrated such as thermally conductive plastics, thermally conductive rubbers, and thermally conductive adhesives. Covers measurement methods, thermal conductivity mechanisms and models Introduces thermally conductive polymers, intrinsically thermal conductors, fillers and composites, as well as interfaces Reviews advances in classification and processing techniques

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the main methods used for thermal properties measurement. It aims to be accessible to all those, specialists in heat transfer or not, who need to measure the thermal properties of a material. The objective is to allow them to choose the measurement method the best adapted to the material to be characterized, and to pass on them all the theoretical and practical information allowing implementation with the maximum of precision.
