摘要: Abstract In this study, heat transfer of air-water-vapour mixtures in a desalination plant, using the aero-evapo-condensation process is studied experimentally. The present consists falling film evaporator and condenser. prototype designed to work at low temperatures (60°C–90°C) geothermal energy. Two experimental pilots were developed. These latter, installed respectively France south Tunisia supplied by fuel results highlighted critical flow rate, characterising phenomenon breakdown. At value, maximum amount evaporated water was obtained. Experimental compared with those derived from model developed Bourouni et al. [1] previous investigation. From comparison it can be learnt that well able predict mass evaporator. This will help optimise component units.
