Numerical Solution of Diffusion Model of Brown Stock Washing Beds of Finite Length Using MATLAB

In the present study, numerical results are obtained for the solution of mathematical model related to diffusion-dispersion during flow through multiparticle system. The "pdepe" solver in MATLAB source code is applied on the axial domain of the system of governing partial differential equations. Numerical results thus obtained are compared with earlier workers analytically and numerically. The comparison shows that results are in good agreement with both analytically as well as numerically. The technique used in the present investigation is simple, elegant and convenient for solving two point boundary value problems with varying range of parameters.
