摘要: Unsteady cooling of a long slab by asymmetric heat convection is analyzed within the framework lumped parameter model. As application classical model limited to values Biot numbers less than 0.1075, we propose improved models that can be applied in transient conduction with larger numbers. The proposed are obtained through two point Hermite approximations for integrals. Closed form analytical solutions given models. It shown comparison reference finite difference solution original distributed higher order (H1,1/H0,0 approximation) yields significant improvement average temperature prediction over
