A plane wall with constant properties is initially at a uniform temperature T O . Suddenly, the surface at x = L is exposed to a convection process with a fluid at T ∞ ( > T O ) having a convection coefficient h . Also, suddenly the wall experiences a uniform internal volumetric heating that is sufficiently large to induce a maximum steady-state temperature within the wall, which exceeds that of the fluid. The boundary at x = 0 remains at T O . (a) On T − x coordinates, sketch the temperature distributions for the following conditions: initialcondition ( t ≤ 0 ) , steady-state condition ( t → ∞ ) , and for two intermediate times. Show also thedistribution for the special condition when there is no heat flow at the x = L boundary. (b) On q x n − t coordinates, sketch the heat flux for the locations x = 0 and x = L , that is, q x n ( 0 , t ) and q x n ( L , t ) , respectively.
