This study aimed to determine how reliable the Transient Plane Source (TPS) method is when testing semi-transparent materials that have varying extinction coefficients at different temperatures. A numerical experiment has been designed that copies the experimental process and tests the accuracy of the thermal conductivity values that the TPS method generates for semi-transparent materials. After using the TPS Method and comparing the results with the numerical experiment, the study concluded ...
Composite materials are materials made of reinforcing substances that are set in a matrix of polymers, ceramics or metals. This experiment measured the thermal conductivity of wood and ceramics, and explored the factors that influence the thermal conductivity. The Transient Plane Source (TPS) method was used because test times are relatively short compared to steady state techniques, and transient methods are not limited by the size, shape, or state of ...
To improve the overall product and thermal characteristics of laser sintering of nylon-12, the transient plane source (TPS) method was used to measure the thermal conductivity of nylon-12 powder. The spiral nickel sensor of was sandwiched between the samples of nylon-12 powder packed at 0.547 g/cc, and as the temperature of the sample rose from 40 °C to 170 °C, the thermal conductivity increased linearly. Knowing these trends will help to make ...
Thermal Constants Analysers are designed to test three-dimensional samples with sizes at least as large as the sensor itself. However, this study examines the possibility of using methods to test the thermal conductivity of thin solid samples when they are thermally insulated. To accomplish this, the 200 data points that are collected by TPS methods should be collected while the sample is heated for only 5 seconds, which is a shorter amount ...
As green energy becomes increasingly important, more companies are exploring the possibility of using molten salts as heat transfer fluids for concentrated solar power. One of the downfalls of molten salts is their low thermal conductivity, which can be altered with the addition of thermally conductive nanoparticles. The thermal conductivity analyzer was used in this experiment to measure the thermal conductivity of molten salts after the addition of MoS2 (molybdenum ...
