RT Journal Article ID 03aa0968512b0254 A1 Ganji, Davood Domiri A1 Ebrahimian, Vahid T1 A General Lumped Model for Unsteady Heat Conduction of an Asymmetric Cylinder and Unsteady Couette Flow JF Heat Transfer Research JO HTR YR 2006 FD 2006-02-22 VO 37 IS 1 SP 1 OP 20 AB The goal of this paper is to show the application of lumped heat-conduction and fluid-mechanics models in engineering problems. Two-dimensional unsteady heat-conduction problem for an asymmetric cylinder is analyzed by this model and the results are compared with the ones of the numerical method. One-dimensional unsteady heat conduction for the slab, infinite cylinder, and sphere problems and also the Couette problem are analyzed using this model and the results of these analyses are compared with the ones of the exact solution. The results show that the step responses gained for these problems within the lumped model are in good agreement with the numerical and exact solutions.
