The improved lumped models were obtained through two-point Hermite approximations for integrals. Transient combined convective and radiative cooling of three-layer composite slabs was analyzed to illustrate the applicability of the proposed lumped models, with respect to different values of the Biot numbers, the radiationconduction parameter, the dimensionless thermal contact resistances, the dimensionless thickness, and the dimensionless thermal conductivity. It was shown by comparison with numerical solution of the original distributed parameter model that the higher order lumped model (H1,1/H0,0 approximation) yielded significant improvement of average temperature prediction over the classical lumped model. In addition, the higher order (H1,1/H0,0) model was applied to analyze the transient heat conduction problem of steel-concrete-steel sandwich plates.Submitted by Jairo Amaro (jairo.amaro@sibi.ufrj.br) on 2019-07-02T17:11:13Z No. of bitstreams: 1 2011_SU_ATE_v31_p2508-2517-min.pdf: 755668 bytes, checksum: 4967ecc68545accd99b4f2fc80959a4b (MD5)Made available in DSpace on 2019-07-02T17:11:13Z (GMT).
