摘要: The unsteady cooling of a long slab by symmetric heat convection is controlled single Biot number Bi = hL/k applied at both surfaces. It known that the thermal response may be analyzed with lumped model small error whenever < 0.1. This paper deals plausible extension implicating an asymmetric two numbers: Bi1 Lh1/k left surface and Bi2 Lh2/k right surface. question needs to addressed following: under what circumstances can treated model?
