Results of the Numerical Simulation of the Entropy Flow Generated at the Fluid Flow with Friction and Heat Exchange

Abstract:

The minimization of the entropy generation is fundamental for the thermodynamic design. Based on theoretical relations contained in the references [1,2,3,4], a numerical simulation program of the entropy flow generated at the flow with friction and heat exchange was developed, whose results are included herein. From their analysis it is clear that between irreversibility and design parameters there isn’t a monotonous dependence, and that, by the mere intuition, without a directed concern, we cannot predict the effect of a design change on the global configuration of irreversibility.
