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 a fluid at 300 K with a heat transfer coefficient of 100 W / m2-K. Determine the heating temperature and temperature distribution across the wall.
include
