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 paper, the thermal conductivity of rock samples was tested using three different methods: the transient plane source (TPS) method, the divided bar method, and calorimetric method. Two rock samples were tested under the TPS method with different procedures (i.e. heating and cooling times, sizes of samples). The results of the TPS method were slightly lower than the results of the divided bar method, but yielded an acceptable ...

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 ...

Water is being used to absorb incident light for use in solar power applications. Adding nanoparticles to water improves the solar collection efficiency. In this paper, a Thermal Analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluids increased with temperature and nanoparticle concentration....

Controlling the temperature of electronics under harsh conditions is important for vehicular, aerospace, and other industrial applications. Phase change materials (PCMs), such as paraffin, use latent thermal energy storage (LTES) to store large amounts of latent heat over small temperature ranges, and are being investigated for use in industrial sectors. However, PCMs have low thermal insulation capabilities so porous matrices with low thermal conductivities are often used to decrease the ...
