Abstract

In this paper, the entropy generation of a flow through a movable plate with variable temperature is studied. Suitable similarity variables are applied to transform the local entropy generation rate to entropy generation number. A modified differential transform method (DTM) with shooting method is used to obtain the similarity solution of the entropy generation. The effects of different parameters (Prandtl number, variable wall temperature) on the irreversibility (such as Nsh, Nsf, Nsx) are analyzed and discussed. Moreover, it is worth mentioning that DTM is of advantage because its numerical solution is differentiation and integration. Therefore, its analysis result is reliable and high accuracy.
