Consider a plane composite wall that is composed of three materials. Given the thermal conductivities k= 1.5 W/m.K and k = 1.75 W/m.K thicknesses LA -40 mm, L= 25 mm, Lc= 30 mm and the contact resistance at the interface between the two materials (A, and B) is known to be 0.30 m².K/W. Material A adjoins a fluid at 35°C for 2 which h=10 =W/m².K, and material C adjoins a fluid at 22°C for A which h= 20 W/m².K. Given that the temperature Tsi = 31°C.

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.
