Abstract

This paper outlines a procedure for obtaining the entropy gene ration number for a fluid flowing in a heat exchanger subjected to a constant wall heat flux. The entropy generation number, N, was defined by Bejan as: N = (T/q)(dS/dl). It will be shown that N may be expressed as a function of mass flow rate and tube inside diameter for the conditions considered. Once this is done the optimum tube diameter for a range of flow rates in the tube may be determined by varying tube diameter and fluid mass flow rate simultaneously, while calculating the entropy generation numbers.
