Abstract

Concentration polarization over a flat plate reverse osmosis membrane is studied analytically. Continuity and momentum equations are solved for a fully developed flow over a flat plate permeating water. The solution is then substituted into the diffusion which governs the concentration distribution for such flow. Separation of variables technique is used to obtain a closed form solution for concentration distribution in terms of Bessel functions of both the first and second kind (Weber's function). This solution is useful in designing reverse osmosis systems using both sea and brackish water as well as similar physical problems.
