The transient plane source method is used to measure the thermal conductivity, thermal diffusivity and the specific heat of solid and some liquid materials. With an instrument, a double spiral nickel sensor is sandwiched between two homogenous samples, and as the sensor pulses electrical currents through the sample, it simultaneously measures how long it takes for the temperature of the sample to increase. Assessment of cob walling should take place ...
In this study, the thermal conductivity, thermal diffusivity, and specific heat of various wall decorative materials were measured using the transient plane source (TPS) technique. Additionally, the thermal emittance of materials painted with acrylic and ceramic paints were measured after the objects were exposed to sunlight....
Nanofluids are used in heat sink applications to improve the rate of heat dissipation and reduce temperature gradients in electronics. This study specifically examined the thermal properties of Al2O3-H2O nanofluids used in micro heat sinks. An instrument measured the thermal conductivity of the Al2O3-H2O nanofluids using the transient plane source (TPS) method. Results showed that, as expected, thermal conductivity increased with the concentration of ...
Porous monoliths, often referred to as polymerised High Internal Phase Emulsions (polyHIPEs), are materials made of polymers that have applications ranging from chemical engineering to biomedicine. In this paper, a TPS instrument measured the thermal conductivity of tannin-based monoliths with the transient plane source (TPS) technique. Results showed that as the porosity of the polyHIPEs increased, the thermal conductivity decreased linearly, a characteristic that could be used for applications in ...
Thermally conductive nanoparticles are often added to conventional fluids to improve thermal properties. In this paper, the effect of small concentrations of multiwalled carbon nanotubes (MWCNTs) on thermal conductivity over a range of temperatures was tested. A Thermal Constant Analyser measured the thermal conductivity of the nanofluids with the transient plane source (TPS) method from 10 to 80 °C. Results showed that thermal conductivity of the nanofluids increased with temperature, and with ...
