Preface

First of all, COFRET is an acronym coming from the French expression “ Co lloque Fr ancophone en E nergie, E nvironnement, Economie et T hermodynamique”, meaning Conference on Energy, Environment, Economy and Thermodynamics . Thus, COFRET is a scientific event initiated in 2002 by an enthusiastic Franch-Romanian group with the aim of organizing a conference on energy, the environment, the economy and thermodynamics every two years, once in France and another time in Romania. Professor Michel Feidt from the University of Lorraine-France, and Professors Stoian Petrescu and Vsevolod Radcenco from the “Politehnica” University of Bucharest-Romania are the founders of this international conference of French-speaking origin. Since its creation, COFRET has sought to bring together specialists from academia and industry to present their achievements and thus, to create opportunities for collaboration in the fields of energy, environment, economy and thermodynamics.
