The improved lumped models are obtained through two point Hermite approximations for integrals. For linearly temperature-dependent thermal conductivity, it is shown by comparison with numerical solution of the original distributed parameter model that the higher order lumped model (H1;1=H0;0 approximation) yields significant improvement of average temperature prediction over the classical lumped model. A unified Biot number limit depending on a single dimensionless parameter b is given both for cooling and heating processes.Submitted by Jairo Amaro (jairo.amaro@sibi.ufrj.br) on 2019-07-15T18:12:54Z No. of bitstreams: 1 2009_SU_AMM_v33_p274-283-min.pdf: 157012 bytes, checksum: 09abd3d7087ff6b28ebcdcbfd8729322 (MD5)Made available in DSpace on 2019-07-15T18:12:54Z (GMT).
