The researchers proposed a method used to measure the thermal conductivity and heat capacity of low thermal conductivity materials with accuracy better than 10%. DSC was also used to determine thermal contact between the sample and the DSC furnace....
Since there was no literature on using the transient plane source method for the measurement of thermal conductivity and diffusivity of food products the authors did it themselves. They tested a variety of products including water, mineral oil, ethanol, beef, chicken and apples and determined that using the transient plane source method to simultaneously measure thermal conductivity and diffusivity was an accurate method....
The authors present a new (at the time) design for the transient hot wire method. Using this method, the thermal conductivity of materials was measured by the slope of a temperature versus time line. The instrument can measure temperatures between 20°C and 200°C with pressure as low as 10 mTorr. The presented method gave good accuracy and precision....
This article outlines the effect of adding Al2O3 and Cu nanoparticles to water and measuring the thermal conductivities and viscosities of the mixtures. The effect of pH was taken into account and it was found that there are optimal pH values for each of the nanoparticle mixtures that give the highest thermal conductivities and lowest viscosities. Research shows that thermal conductivity and viscosity are closely related to each other. ...
Using the TPS method, the authors measured the thermal conductivity and thermal diffusivity of samples of Swedish wood. They also looked at the effect of density, porosity and anisotropy on the measured thermal properties. Both longitudinal and transverse measurements were taken at temperatures ranging from 20°C to 100°C and an increase in temperature resulted in a slight increase in thermal conductivity. The types of mechanisms that lead to heat conduction ...
