Energetic transition within thermal machines and co-generation: effect of mass flux on critical heat flux

Topics associated with the critical heat flux (CHF) in industry sector are at the heart of the hot interesting issues on the global agenda. In this paper, we introduce a new method of energy analysis of heat transfer in new generation heat exchangers applicable to the innovative sector of energy recovery. A statistical analysis is performed to study the effect of mass flux on the critical heat flux of an evaporator boiler. The aim of the present study is to provide insights into the effect of mass flux on the CHF when porous tubes are used. Independent sets of full 23 factorial designs with three central points were employed in case of porous coated tubes. Results revealed that the CHF could be influenced by some factors which were dominated in the studied conditions. More specifications of CHF and its relation with the input variables were detailed in this paper.
