Effects of Thermal Conduction in Sonoluminescence [PDF]

The Journal of the Acoustical Society of America, 1963
Current experimental results indicate that sonoluminescence is largely thermal in origin, with the spectra showing a direct relation between luminous intensity and the temperatures generated inside the collapsing cavitation bubbles. In the present paper, the strong dependence of the luminous intensity on the nature of the gas dissolved in the liquid is

Effective thermal conductivity of wire-woven bulk Kagome sandwich panels

Theoretical and Applied Mechanics Letters, 2014
Thermal transport in a highly porous metallic wire-woven bulk Kagome (WBK) is numerically and analytically modeled. Based on topology similarity and upon introducing an elongation parameter in thermal tortuosity, an idealized Kagome with non-twisted ...

Laboratory Investigation of Heterogeneous Metamorphic Rocks and Their Spatial Distribution of Thermal Conductivity

Energies
Assessing the variation in the thermal conductivity of heterogeneous rock materials can be critical when upscaling models to simulate geothermal system operation, especially for petrothermal systems, where conduction dominates over convection. This study’

Effects of defects on the effective thermal conductivity of thermal barrier coatings

Applied Mathematical Modelling, 2012
Abstract It is difficult to establish structure-property relationships in thermal barrier coatings (TBCs) because of their inhomogeneous-geometry microstructures caused by defects. In the current research, the effects of pores and cracks on the effective thermal conductivity of TBCs are studied.

THE EFFECT OF DISLOCATIONS ON THERMAL CONDUCTIVITY

Le Journal de Physique Colloques, 1981
Phonon scattering by the strain fields of deformed crystals is formulated in terms of the third order elastic constants. The thermal restivity due to dislocations is calculated. Theory and experiment are in accord for Cu, Al, Ge and Si but not for LiF.
