Theoretical analysis and verification of concentration distribution model in the ultrafiltration process

Based on the assumed flat model, Navier–Stokes equation for two-dimensional laminar flow fluid and the theory for diffusion and mass transfer, we obtained theoretical results with regarding to the concentration distribution in separation process by mass transfer model in the ultrafiltration process. Through theoretical analysis and experimental verification of concentration distribution, it was known that this model could not only preferably describe the concentration distribution of ultrafiltration process but also forecast concentration polarization phenomenon.
