Thermal Diffusion and Convective Stability
The Physics of Fluids, 1972The stability of a two-component fluid layer subjected to a temperature gradient has been studied, and the associated thermal diffusion separation has been found to exert a large influence even when the separations are small. The most unexpected and perhaps important result is that an instability has been found which can give rise to convection ...

Thermal Diffusivity Measurements of Thermographite
International Journal of Thermophysics, 2004This paper presents results of measurements of a graphite proposed to serve as a thermophysical property reference or standard reference material. The reported measurements contribute to a program launched in 1999 by Anter Corp. with the objective to provide a replacement for the NIST thermal property reference material RM AXM-5Q graphite whose ...

We describe applications of fast IR cameras to map the thermal diffusivity of a slab of material. The methodology is based on curve-fitting techniques like those described at the 1998 Review of Progress in QNDE. We will present a comparison between results obtained using a laboratory camera with those obtained using a portable camera suitable for field

Thermal Conductivity and Thermal Diffusivity
1983Abstract This chapter presents basic principles and the theoretical results of heat transport in solids. Thermal conductivity and thermal diffusivity are the principal properties discussed. Discussions are also included on the effects of temperature, magnetic field, and metallurgical variations caused by composition, processing, and heat-

Thermodiffusion (thermal diffusion)
2000Es handelt sich um einen sog. Kopplungs- oder Kreuzeffekt in einem Mehrkomponentensystem. Dieser Effekt besteht im vorliegenden Fall aus Diffusionsstromen der Komponenten eines Gemisches aufgrund eines Temperaturgradienten.
