For decades, the solution-diffusion model has been the prevalent approach to describe water transport mechanism in RO membranes. In this model, water first partitions into the membrane and then diffuses down a concentration gradient of water within the RO membrane. However, recent experimental and ...

This study focuses on solution of mathematical model related to diffusion-dispersion via separation of variables and Laplace transform. The solute is assumed to be uniformly distributed throughout the packed bed. Before solving, model is converted into dimensionless form by using Peclet number, ...
leads to the regularized Perona Malik model with an edge indicator function .We suppose to be a monotone decreasing function chosen such that and where is constant,e.g. ,with .As already mentioned above the convolution avoids the non-wellposedness of the model.A widespread choice is the convol...
Therefore, based on the solution-diffusion model, the permeability depends on solubility (S) and diffusivity (D) coefficients and can be determined using the following equation [19,29]: (4)P=S×D Accordingly, the ideal selectivity of a membrane toward a gas pair is determined by the ratio ...
A microcomputer model for the sparging of aquifers contaminated with volatile organic compounds (VOCs) is presented which includes the kinetics of solution of nonaqueous phase liquid (NAPL) droplets and of diffusion from low-permeability porous layers. The well configuration modeled is a horizontal slo...
