Novel Measurement of Anisotropic Thermal Diffusivity
نویسندگان
چکیده
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 in three orthogonal directions.

Thermal Characterization of Multi-wall Carbon Nanotube Bundles Based on Pulsed Laser-assisted Thermal Relaxation
A novel transient technique is developed to measure the thermal diffusivity of one-dimensional microscale wires. In this technique, a pulsed nanosecond laser is used to quickly heat the wire. After laser heating, the wire temperature decays slowly. Such temperature decay is sensed and used to determine the thermal diffusivity of the wire. A 25.4μm thin Pt wire is characterized to verify this te...

In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...
