Temperature profiles are calculated for steady-state conduction through a series of three walls with different thermal conductivity. There is also a contact resistance between each pair of walls. Heat is generated at a constant rate in either wall

A

or

B

(select using buttons). Set the rate of heat generation and the contact resistance between the walls with sliders. The distance between the walls is exaggerated so that the temperature profile is more easily seen. The left side of wall

A

is insulated, and heat is transferred from the right side of wall

C

to the flowing air, which is at 20 °C.
