A bar of thermal conductivity k = 140 W/m ⋅ K is of a trapezoidal cross section as shown in the schematic. The left and right faces are at temperatures Th = 100°C and Tc = 0°C, respectively. Determine the heat transfer rate per unit bar length using a finite difference approach with ∆X = ∆y = 10 mm. Compare the heat rate to that of a bar of a 20 mm × 30 mm rectangular cross section where the height of the domain is 20 mm.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
