A plate of thickness 2L, surface area As, mass M, and specific heat cp, initially at a uniform temperature Ti, is suddenly heated on both surfaces by a convection process (T∞, h) for a period of time to, following which the plate is insulated. Assume that the midplane temperature does not reach T∞ within this period of time.
(a) Assuming Bi ≫ 1 for the heating process, sketch and label, on T–x coordinates, the following temperature distributions: initial, steady-state (t →∞), T(x, to), and at two intermediate times between t to and t →∞.
(b) Sketch and label, on T – t coordinates, the midplane and exposed surface temperature distributions. (c) Repeat parts (a) and (b) assuming Bi ≪ 1 for the plate.
(d) Derive an expression for the steady-state temperature T(x, ∞) Tf, leaving your result in terms of plate parameters (M, cp), thermal conditions (Ti, T∞, h), the surface temperature T(L, t), and the heating time to.
