Extending the flash method to measure the thermal diffusivity of semitransparent solids

In this work, we extend the classical flash method to retrieve simultaneously the thermal diffusivity and the optical absorption coefficient of semitransparent plates. A complete theoretical model

Photothermal spectroscopy: A promising tool for nanofluids

In recent years, the demand for more efficient cooling circuits has resulted in active studies of nanofluids, two-component liquids consisting of a base fluid, and dispersed nanoparticles with high

Experimental Validation of Formula for Calculation Thermal Diffusivity in Superlattices Performed Using a Combination of Two Frequency-Domain Methods: Photothermal Infrared Radiometry and Thermoreflectance

In this paper, we validate two theoretical formula used to characterize thermal transport of superlattices at different temperatures. These formulas are used to measure cross-plane thermal

Toolbox for modeling frequency-domain photothermal experiments on multilayers

A general expression (master equation, ME) is derived for the thermal impedance in photothermal experiments in a multilayer system, based on one-dimensional (1D) periodic heat diffusion. The ME in a

Measurement of the thermophysical properties of self-suspended thin films based on steady-state thermography.

A steady-state IR micro-thermography with simplified measurement procedure and new data processing method was suitable for analyzing thin films with a wide range of thermal properties and the background thermal radiation was eliminated.

Generalized expression for the self-normalized signal in photothermal experiments for multilayered materials in the frequency domain

The analytical solution for diffusion of heat for a four-layered material, in a surface absorption model, is used to describe a simple diagram-based construction methodology for obtaining the

Thermal conductivity profile determination in proton-irradiated ZrC by spatial and frequency scanning thermal wave methods

Using complementary thermal wave methods, the irradiation damaged region of zirconium carbide (ZrC) is characterized by quantifiably profiling the thermophysical property degradation. The ZrC sample
