modeling simulation and analysis of molecular distillators centrifugal and falling film
Computers & Chemical Engineering, 1996Co-Authors: C B Batistella, M R W MacielAbstract:A description of the molecular distillation process is made in order to show its principal applications for chemical processes. The transfer process from liquid stage for the falling film and centrifugal molecular distillators is described. The liquid film flows in the conic rotative evaporator of the centrifugal distillator and in the cylindric evaporator of the falling film distillator. The equations that characterize both processes are the mass, energy and momentum balances and the Langmuir Rate of Evaporation. The equations are solved by the method of finite differences. The effect of several parameters on the distillation Rate and on the separation efficiency are studied for binary systems. A comparative analysis between the falling film and centrifugal distillation apparatuses is carried out.

Structural and evaporative evolutions in desiccating sessile drops of blood
Physical Review E : Statistical Nonlinear and Soft Matter Physics, 2011Co-Authors: B. Sobac, David BrutinAbstract:We report an experimental investigation of the drying of a deposited drop of whole blood. Flow motion, adhesion, gelation, and fracturation all occur during the Evaporation of this complex matter, leading to a final typical pattern. Two distinct regimes of Evaporation are highlighted: the first is driven by convection, diffusion, and gelation in a liquid phase, whereas the second, with a much slower Rate of Evaporation, is characterized by the mass transport of the liquid left over in the gellified biocomponent matter. A diffusion model of the drying process allows a prediction of the transition between these two regimes of Evaporation. Moreover, the formation of cracks and other events occurring during the drying are examined and shown to be driven by critical solid mass concentrations.

different parameters affecting the Rate of Evaporation and condensation on passive solar still a review
Renewable & Sustainable Energy Reviews, 2014Co-Authors: Muthu A Manokar, Kalidasa K Murugavel, G EsakkimuthuAbstract:Scarcity for water exists in many countries even though three-fourth of the earth is covered by water. The reasons for scarcity of water are worldwide rapid growth of industry and immeasurable population. Solar still is the only efficient solution for water problem in hot climatic conditional areas where scarcity of water and electricity occurs. Solar still is a very simple solar device that is used for converting the available brackish water into potable water. Investigation shows that the productivity of basin type solar still is limited. Various literature reported several experimental and numerical investigations on basin type of solar still. An extensive review on different parameters affecting the Rate of Evaporation and condensation on passive solar still has been carried out in this paper.
