  1. 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...

  2. 1D Transient Heat Conduction CDF Tool

    site

    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.

  3. CDF Tools for Heat Transfer

    site

    This page contains a directory of sub-pages that use Mathematica-based embedded CDF tools for solving analytical problems in heat transfer. To download the required, free CDF player click here Sub-Pages 1D Transient Heat Conduction CDF Tool Boundary Layer Flow Solution Fin Temperature CDF...

  4. Fin Temperature CDF Tool

    site

    Calculation of Fin Temperature for Adiabatic Tip and Infinite Fins The following CDF tool calculates the normalized fin temperature (θ(x) / θbase) for two cases: Case 1: Adiabatic fin tip Case 2: Infinitely long fin In both cases, the cross sectional area of the fin is assumed...

  5. ZT to COP Thermoelectric CDF Tool

    site

    Conversion of ZT of a Thermoelectric to Refrigeration COP The tool below is based on the Mathematical Computable Document Format (CDF). To download the required, free CDF player click here The tool uses the following formula for the ZT to COP (refrigeration) conversion: math_failure...

  6. Derivation of Planck's Law

    site

    About this page This page provides a brief derivation of Planck’s law from basic statistical principles. For more information, the reader is referred to the textbook by Rybicki and Lightman (Radiative Processes in Astrophysics, Wiley, 2004) [1]. The reader might also find interest in the...

  7. Boundary Layer Flow Solution

    site

    Boundary Layer for Flow Past a Wedge The Blausius boundary layer velocity solution is a special case of a larger class of problems forflow over a wedge, as shown in the following figure in which βπ represents the wedge angle. wedge_bl.png The general solution is called the Falkner-Skan...
