Notes on the quantum of thermal conductance
The following is a dump from LaTex, just to see what happens…
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...

Microscale Energy Transport
A great deal of research in heat transfer is devoted to understanding energy transport at reduced scales. This page serves as a starting point for graduate-level content related to microscale heat...
In this topic 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 expression for how much heat a given acoustic phonon branch, or polarization, can...

The Solar Constant
The solar constant is the heat flux from the Sun.
T=5762K; Radius of Sun, RS = 6.96x10 − 8m; SES = 1.496x1011m;
Metals: good reflector due to free electron

Purdue ME 606: Enclosure Characteristics (Lecture 9)
For an enclosure with N black surfaces, the energy leaving a surface i is qi(leaving) = EbiAi. The energy arriving from another surface (noted as j) equals qi = EbjAjFji. For all N surfaces the net heat incident on surface i is,
Thus, the net energy flow to surface i in an...

Partial Differential Equations
In a partial differential equation, the dependent variable depends on two or more independent variables.
The Laplace equation is a PDE, because f is a function of two variables; x and y.
