Consider a circumferential fin of rectangular profile as shown in Figure 2-12. Set up nodal equations for a fin of thickness t, heat transfer coefficient h, thermal conductivity k, and heat generation rate q as a function of radial coordinate r, taking increments of ˆ†r. Write the nodal equations for the node adjacent to the base temperature T0, a node in the middle of the fin, and the node at the end of the fin.
