Plane wall with constant properties is initially at a uniform temperature to. for t> 0, the surface at x=l is exposed to a convection process with a fluid at a temperature greater than to. the convection coefficient is h. the boundary at x=0 remains constant at to. a) assuming no internal heat generation, simplify the heat conduction equation and sketch the temperature versus x for t=0, steady-state, and two intermediate times. b) assuming that for t> 0, the wall experiences uniform internal heat generation that is sufficiently large so that the maximum steady-state temperature within the wall is higher than the free stream temperature. on t-x coordinates, sketch the temperature distributions for the following conditions: initial condition, steady-state, and two intermediate times. c) plot the flux versus time for locations x=0 and x=l.
