Abstract |
A finite difference solution for reverse osmosis in turbulent flow is presented. The case of a flat duct made of two parallel semi-permeable membranes is considered. The pertinent diffusion equation with the eddy diffusivity based on Deissler's expression is solved using a two-step linearized finite difference scheme, taking into account the nonlinear effect due to the varying water flux across membrane along the axial direction. Numerical results relating concentration polarization, water flux, Sherwood number water recovery ratio and operating conditions are given for a variety of cases. (Author) |
