Pervaporation Mathematical Model
(OP)
I need a mathematical model for Pervaporation for simulation. Any book/url/helpful tip may work. Thanks in advance.

RE: Pervaporation Mathematical Model
you may look for this literature:
A. Heintz, W. Stephan: A generalized solution-diffusion model of the pervaporation process through composite membranes
Part I. Prediction of mixture solubilities in the dense active layer using the UNIQUAC model, Journal of Membrane Science 89(1994)143-151.
A. Heintz, W. Stephan: A generalized solution-diffusion model of the pervaporation process through composite membranes
Part II. Concentration polarization, coupled diffusion and the influence of the porous support layer, Journal of Membrane Science 89(1994)153-169.
Heintz and Stephan used PVA/PAN membranes for their water/alcohol separation experiments and simulation, resp.
Please note: Influence of liquid boundary layer and the membrane support, resp., can be essential and should allways be considered!
B.K. Srinivas, M.M. El-Halwagi: Optimal design of pervaporation systems for waste reduction, Computers chem Engng, 17(1993)957-970.
Connection of several PV stages for optimal network operation.

Thanks for your help. The references ypu have suggested are more on the Sorption-Diffusion modeling of pervaporation. I'm working on the Pore flow model of Pervaporation. Still I'm stuck up at the determination/calculation of the surface viscosity. Please can you help me in that respect?Thanks.
