Measurement Thermal Conductivity and Thermal Diffusivity of Chromium Nanofluids
In this study, nanofluids of Chromium (Cr) in water, Ethylene Glycol and Ethanol have been prepared using single step method. The thermal conductivity and diffusivity of these nanofluids were measured via hot wire-photothermal deflection technique. Based on finite difference method (FDM) temperature distribution and photothermal deflection caused by the hot wire inside nanofluids was obtained. ...
متن کاملEffective thermal conductivity in thermoelectric materials
Thermoelectric generators (TEGs) are solid state heat engines that generate electricity from a temperature gradient. Optimizing these devices for maximum power production can be difficult due to the many heat transport mechanisms occurring simultaneously within the TEG. In this paper, we develop a model for heat transport in thermoelectric materials in which an " effective thermal conductivity ...
متن کاملNovel Measurement of Anisotropic Thermal Diffusivity
We describe a method for the measurement of thermal diffusivity of anisotropic materials. The technique uses a single pulse of light from a flashlamp on the front surface of a slap of material, part of which is shadowed by a rectangular mask. By fitting the measured rear surface temperature distributions as a function of time and space to a theoretical model, we obtain the thermal diffusivities...
متن کاملComparison of thermal diffusivity measurement techniques
Thanks to the collaboration between two laboratories, we present different techniques to measure thermal diffusivity. A brief description of any technique both in the experimental layout and in the processing algorithms is given. Results obtained on samples cut from the same block of stainless steel AISI 304, are reported. Uncertainty evaluation of any measurement is reported as well.
متن کاملRadiative Thermal Diffusivity and Conductivity of the Upper Mantle
Olivine comprises >60% of the upper mantle, making it the dominant control on heat transport through the lithosphere. Accurate estimates of the thermal diffusivity and thermal conductivity are important to modeling geotherms, estimating lithospheric thickness, determining the depth range of melt generation, etc. Diffusivity and conductivity result from lattice vibration and radiative transport ...
