Unformatted text preview: temperature of the steel plate is 300 K. a) Assuming the thermal conductivity is independent of temperature, solve for the temperature at the interface of the aluminum and steel plates. Calculate the heat flux conducted through the composite solid. k Al = 205.9 W/m·K (averaged value over 300 to 450 K) k steel = 45.1 W/m·K (averaged value over 300 to 450 K) b) Assuming the thermal conductivity varies linearly with temperature, solve for the temperature at the interface of the aluminum and steel plates. Calculate the heat flux conducted through the composite solid. k Al (T) = (0.464 W/m·K 2 ) T + 32 W/m·K k steel (T) = (0.021 W/m·K 2 ) T + 53 W/m·K Problem 3 A plane wall (infinite in the y and z directions), has internal heat generation per unit volume which varies according to L x e q q / β= & & . The boundary conditions which apply are T = T at x = 0 and T = T L at x = L . Solve for the temperature distribution in the wall. Assume steady state and no viscous dissipation....
