The purpose of the demonstration below is to illustrate the relationship between heat transfer and thermal conductivity of a material by applying Fourier's law, , to plot the temperature versus the position through the depth of a multilayer wall. You can vary the total heat surface heat flux conducted through the multilayer wall and the surface temperature at the far left side of the wall, . The wall has a constant cross-sectional area in square meters in the direction. You can select different materials and their thicknesses for five layers of the wall, denoting as the thermal conductivity of layer . Given this information, it is possible to determine the temperature profile through the wall, showing the interior temperature at each location.
