The Transient Plane Source Method is a helpful tool to test for the thermal conductivity of homogenous materials, however researchers at both the Chalmers University of Technology and Gothenberg University have created a process to test the thermal conductivities of inhomogeneous materials. For this experiment, a thermal analyzer was used to determine the thermal conductivities of four different sample materials (polymers and Pyrex glass) – each with different sizes and defects. ...
Barium titanate-based ceramics are most commonly found in electronics as dielectric layers in multilayer ceramic capacitors. Two different forms of Barium titanate-based ceramics were analyzed in this article to determine heat capacities as a function of temperature. The thermal conductivities and thermal diffusivities of these two forms were also determined using the Hot Disk Transient Plane Source method. Inferences towards the performance and reliability of barium titanate-based ceramics under various ...
In this study, the thermal conductivity of alkanes was altered, by using inverse micellar templating and nanofibers. The main goal of this study was to create alkanes with tunable thermal conductivities, for their use as phase change materials in heat management. The thermal conductivity of an n-hexadecane product with inverse micelles of different volume fractions was analyzed. The tunable thermal conductivity of the micelle templated alkaline was determined to be ...
During a melt blending process, carbon nanotubes (CNTs) were added to a poly(vinylidene fluoride)/Boron nitride (PVDF/BN) composite, to increase the thermal conductivity of this polymer composite, for uses in the electronic industry. After this process, the thermal and electrical conductivities, along with any microstructure changes were investigated. It was determined that with the addition of CNTs, the thermal conductivity rating of the composite increased, as well as ...
The field of nanofluids is relatively new, however researchers in this article aimed to research their thermal conductivity and dispersion behaviours. A nanofluid consists of free-floating, solid nanoparticles suspended in a base fluid. Specifically, Al2O3-H2O nanofluids were investigated in this study. Using a thermal constants analyzer, the thermal conductivities of various modifications of nanofluids were measured. Research concluded that pH and concentrations of SDBS dispersants have a ...
