Condensation

Different theoretical and experimental studies carried out in the field of solar distillation with green-house effect, have shown that global efficiency of a simple solar still are affected by physical and building parameters, especially by the difference of temperature between the evaporation surfa

Condensation of steam and steam from non-condensable gases were investigated experimentally inside a vertical tube. The consistency and reliability of the measurements were checked by detailed energy balance. The experimental results show the effect of non-condensable gases on heat and mass transfer

The effects of liquid load, tube diameter, evaporation boiling point, condensation temperature difference and steam flow velocity on the heat-transfer film coefficients inside horizontal tubes were studied. The experiments were conducted with various operation parameters. In fact, if there is little

Horizontal-tube falling film condensers are used in many fields: chemical industries, refrigeration, desalination, cooling, etc. However, their performances cannot be predicted precisely due to the complexity of the phenomena. In this paper, heat and mass transfer in a horizontal-tube falling-film c
