A theoretical investigation of thermal waves
… of one-dimensional heat conduction based on thermal relaxation is presented. Thermal relaxation is introduced through the constitutive equation (modified Fourier's law) which relates this heat flux and temperature. The resulting temperature and flux field equations become hyperbolic rather …

ΘΕΩΡΙΑ ΤΟΥ ΠΙΝΑΚΑ ΣΚΕΔΑΣΗΣ ΓΙΑ ΘΕΡΜΟΕΛΑΣΤΙΚΑ ΚΥΜΑΤΑ
… IS CONSTRUCTED FOR SCATTERING OF THERMOELASTIC WAVES IN ISOTROPIC AND THERMALLY CONDUCTING MEDIA. THE T-MATRIX RELATES THE COEFFICIENTS OF THE INCIDENT THERMOELASTIC AND THE COUPLED THERMAL WAVES TO THE COEFFICIENTS OF THE CORRESPONDING SCATTERED WAVES. THE FORMALISM USED IS QUITE GENERAL AND IS …

Chemical and Thermochemical Wave Behavior in Multiphase Fluid Flow Through Permeable Media: Wave-Wave Interactions
… reactive flow. These regions are separated by waves, which mark the change in composition from one region to the next. We develop a theory which elucidates the interactions of these chemical waves with those formed from other flowing phenomena. We consider the following interactions: 1.) the …

New concepts in energy and mass transport within carbon nanotubes
… guides due to their high axial electrical and thermal conductivity. Also, their subnanometer scale with atomically smooth surfaces is promising for selective mass transport in nanoscale, such as molecular transport, selective gas permeation, and nanofluidics. The first part of this thesis …

Estimating The Thermal Properties Of Thin Film And Multilayer Structures Using Photothermal Deflection Spectroscopy
Photothermal deflection spectroscopy (PDS) is an experimental technique which may be used to determine the thermal properties of materials. An intensity modulated heating laser is used to generate periodic thermal waves in the material and the surrounding gas phase. A probe laser is passed through …
