A novel method for calculating partition coefficient of saline water in direct contact membrane distillation: CFD simulation

摘要

For the first time, four different thermodynamic generic equations of state were applied to calculate the water partition coefficient in the polymeric direct contact membrane distillations studied in this research. Peng-Robinson equation of state was found to have the best fit with experimental data. Furthermore, the polymeric membrane performance was studied at different feed flow rate, temperature and cold stream flow rate. In addition, different feed and permeate flow directions were examined and as expected, cross-current flow arrangement showed the highest permeate flux.
