Steady-State Heat Transfer through a Composite Plane Wall
Steady-State Heat Transfer through a Composite Plane Wall
This Demonstration calculates the temperature profile across a composite plane wall. The wall is exposed to convection on both the right and left sides. The central layer has uniform volumetric heat generation. The parameters correspond to thickness and thermal conductivity for each of the three layers, internal heat generation for the central layer, and temperature and convective heat transfer coefficients for the fluids in contact with the wall surfaces on each side. The top graphic displays the nomenclature used for each layer (notice the color coding). The location and value of the maximum temperature within the layer with heat generation is displayed on the top of the plot (only when heat generation is larger than zero). The heat fluxes at each interface between fluid and wall are described at the bottom, followed by the rate of energy per surface area that exits the wall. There are five choices for the axis origin: the left surface of the wall, the interface between the first two solid layers , the center of the layer with heat generation 2, the interface between the second and third wall , or the right surface of the wall.
