THE FINITE VOLUME a composite wall is made of two materials (A with ka = 0.8 W / m-K and B with kb = 4 W / m-K), each with a thickness L = 10 mm. The surface of the wall A at x = 0 is perfectly insulated. A very thin heater is placed between the insulator and material A, giving a heat flow of 4500 W / m2. The wall surface at x = 2L is exposed to...

2. Aluminum fins with rectangular profiles (5 mm wide and 1 mm thick) are used to remove heat from a surface whose temperature is 150°C. The temperature of ambient air is 20°C. The thermal conductivity of aluminium is 168 W/m.K. The natural convective coefficient associated with the surrounding air is 35 W/m2.K. The fins are 150 mm long and the heat loss from the tip of the fin may be neglected. (a) Determine the temperature distribution along...

The heat that is conducted through a body must frequently be removed by other heat transfer processes. For example, the heat generated in an electronic device must be dissipated to the surroundings through convection by means of fins. Consider the one-dimensional aluminum fin (thickness t 3.0 mm, width 20 cm, length L) shown in Figure 1, that is exposed to a surrounding fluid at a temperature T. The conductivity of the aluminum fin (k) and coefficient of heat convection of...
