#### The Melting Snow Castle – a diffusion model application

03/24/2011

This is an application to the previously derived 2D diffusion (heat transfer) model. The snow melting process is very similar to diffusion or heat transfer. Just open the model and hit “Start-Pause” to see for yourself. It is a 2003 model or earlier. I wasn’t able to run it in 2007 with animation but I’ve got some friends who managed to run it with no problem (except speed). The graphics is very…

#### A Basic 2D Animated Heat Transfer Model (a diffusion model too)

03/21/2011

Here is a basic 2D heat transfer model. The first  five worksheets model square plates of 30 x 30 elements. The last worksheet is the model of a 50 x 50 plate. You can modify the initial temperature by hand within the range C21:AF240. It is also a diffusion model. It uses the storage and transport equations derived in the previous tutorials. The temperature calculations are done all  with a single repetitive…

#### Animated Heat Transfer Modeling for the Average Joe – part #4

03/20/2011

This is the last tutorial of the series and it shows how to implement the previously derived formulas into a spreadsheet model. The spreadsheet formulas, the macros and charting of the dynamic data is explained. [sociallocker][/sociallocker]

#### Animated Heat Transfer Modeling for the Average Joe – part #3

03/19/2011

This section shows how to model heat transfer in a linear bar by dividing it in elementary sections in which the basic linear equations introduced in the previous tutorials can be used.

#### Animated Heat Transfer Modeling for the Average Joe – part #1

03/17/2011

This the first tutorial on modeling heat transfer at a very introductory level. If you follow this series and spend your own effort in developing your own models you will be able to model heat transfer in very complex shapes (1D, 2D, 3D) in a short time and with the basic understanding of a 12 year old school boy.

#### A One-Dimensional Dynamic Heat Transfer Model – a diffusion model

03/16/2011

Hi guys, Here is a 1D dynamic model I built today simulating heat transfer in a 21-segment bar. Just click on the orange “Demo” button for a quick demo. Hitting “Reset” sets the 21 segments of the bar to the initial conditions which is a fully customizable initial temperature map. Clicking “Start/Pause” starts the simulation and you can watch the bar temperature profile slowly settling to equilibrium. I recommend you leave the simulation…
