Numerical study of the effect friction coefficient particles on morphological properties of separation membrane surface

Abstract

To understand and improve the performance of membrane separation surface used in the water desalination water process, we have studied the effect of friction coefficient on the morphological properties of retentate deposits particles on the surface membrane separation. The investigation is made in the framework of the Langevin equation model based on the competition between stochastic and particle dissipation mechanisms. The noise coefficient, the friction coefficient, and the constant flow rate are remarkable parameters that influence the average velocity and the average distance between the particles. The results show that the temporal evolution of the mean velocity of retentate deposits particles presents an exponential profile with two different regimes. However, the scaling dynamic studies show that the studied system is governed by scaling exponents more consistent with the Family–Vicsek model.
