Summary
Temperature through a plate heated from the left with an insulated back. Left: small Biot number, the temperature drop sits in the gas layer at the surface. Right: large Biot number, the drop sits inside the solid. Based on Rockett and Milke (2002), p. 1-33, and McGrattan et al. (2026), p. 226.
Original illustration for Biot number, level 4 Expert.
- Source basis: Rockett and Milke (2002), p. 1-33 (plate heated on one face, insulated back; small Bi thermally thin, large Bi not); McGrattan et al. (2026), p. 226 (Bi as ratio of internal resistance to external boundary-layer resistance); Van Rossum (2027), §5.2 (resistances L/λ and 1/hc in series)
- Alt text: Two cross-sections of a heated plate: left, a nearly flat temperature line inside the plate; right, a steep temperature drop inside the plate.
