This simulation calculates the temperature profiles and the heat flux for steady-state conduction through a composite wall that consists of four walls in series. The total wall thickness is 10 cm. Change the temperature of the left side of the compoosite wall with a slider; the temperature of the right side of the composite wall is fixed at 45°C. Change the thickness of the glass, concrete, and stainless steel walls using sliders. Use the dropdown menu to select the material (fiberglass, brick, or lead) of the right wall. The heat flux is the same through each wall.

This simulation was created in the Department of Chemical and Biological Engineering, at University of Colorado Boulder for LearnChemE.com by Mathew Williams and Rachael Baumann under the direction of Professor John L. Falconer, with additional contributions from Nick Bongiardina and was converted to HTML5 by Patrick Doyle, with additional contributions by Neil Hendren. This simulation was prepared with financial support from the National Science Foundation. Address any questions or comments to learncheme@gmail.com.
