Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The transient plane source sensors were used to measure thermal conductivity and other thermophysical properties of infrared transparent materials, while under infrared imaging. The infrared imaging provided evidence of temperature uniformity and symmetry, as well as temperature monitoring of the sensor and material being tested. The upgraded version of the original TPS system was used including a bridge circuit, a digital voltmeter, and a data analysis module...
This research article proposes the use of a thermal constants analyzer to measure thermal properties of relatively thin samples. Five different metallic samples containing copper, aluminum and brass were used to test the accuracy of the new and improved method. Previously, this method has been used to test the thermal properties of thin metallic sheets, however with the new and improved method, it is possible to measure samples with thicknesses ...
Thermal conductivity measurements of the same samples were carried out using the TPS method. Thermal testing on carbon nanotubes to study for promising fillers. Thermal conductivity of single-walled carbon nanotubes should enable a further reduction in the filler content required for a given enhancement in the composite properties. For the multi-walled carbon nanotube thermal conductivity increased modestly using this method whereas for the single-walled carbon nanotubes the thermal conductivity was ...
