Numerical-analytical method for determining the barodiffusion coefficient of technological process of ion-exchange suspension filtration

Abstract A method for determining an experimental parameter of the barodiffusion coefficient for conducting computational experiments in technological process of filtering liquid ionized solutions is given in the paper. The developed mathematical model allows obtaining calculated data for the study of other parameters of the unit, taking into account the physicomechanical properties of fluid when cleaning solutions in an ion-exchange column. An analytical solution to the systems of linear equations of diffusion and mass transfer with a constant flow velocity and a variable pressure gradient is obtained. Using these data we can verify the adequacy of the developed mathematical models of the mass transfer process in porous media.
