HEAT EXCHANGERS: AN ENERGY VIEWPOINT APPROACH.

ETUDE ENERGETIQUE DES ECHANGEURS DE CHALEUR.

Author(s) : BUCHET E.

Type of article: Article

Summary

THIS PAPER PRESENTS A BRIEF DISCUSSION OF THE CONCEPT OF EXERGY. THE AUTHOR THEN STUDIES HEAT EXCHANGE BY CONDUCTION, CONVECTION AND RADIATION AS WELL AS THE IRREVERSIBILITIES. HE SHOWS THE IMPORTANCE OF THE TEMPERATURE LEVEL ON THE HEAT FLUX AND THE EXERGY LOST. THIS ANALYSIS RESULTS ALSO IN CONCLUSIONS ON FINS AND THERMAL INSULATION. HE ALSO STUDIES HEAT EXCHANGERS, IN GENERAL. THE LOSS OF EXERGY DUE TO THE THERMAL EXCHANGE PERMITS A COMPARISON OF THE THERMAL VALUE OF THESE APPARATUS AND SHOWS THE INFLUENCE OF THE ISOTHERMAL CHANGE OF STATE OF A FLUID. DIFFERENT TYPES OF HEAT EXCHANGERS USED IN INDUSTRIAL APPLICATIONS ARE ANALYSED.
