Notes on the quantum of thermal conductance

site

The following is a dump from LaTex, just to see what happens… begin{abstract} In this module we derive the quantum of thermal conductance, and along the way, concepts related to phonon density of states and spatial dimensionality are discussed and applied. The end result is a simple...

1D Transient Heat Conduction CDF Tool

Analytic Solution for 1D Transient Heat Conduction The problem geometry and boundary conditions are shown below. An initially isothermal (Tinitial) semi-infinite medium is suddenly subject to a surface temperature Th.
