A Point of View on Optimum Design of Shell and Tube Heat Exchangers
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2017, Vol 24, Issue 1
Abstract
The concept of irreversibility is described based on theory of second law of thermodynamics. Its understanding followed by the entropy generation minimization is challenges for specialists. Nowadays advanced thermodynamics uses the entropy generation rate as a parameter able to quantify the significance of irreversibilities. Heat exchangers play a major role in the safety performance and economy of ships. The aim of this paper is to offer to marine engineers a tool to deal with optimum design of shell and tube heat exchangers by entropy generation minimization method. The modified entropy generation number is considered as the objective function in the minimization process. Thus, marine engineers’ goal is to minimize the modified entropy generation number in order to increase effectiveness and to decrease pressure drop.
