Abstract
Closed form solution is obtained for dispersion of a solute in a fluid-saturated sparsely packed porous medium using Brinkman model. The time-range of validity of the dispersion coefficient, which increases with time, is widened by using a generalised dispersion coefficient. The effect of porous parameter on the dispersion coefficient is clearly depicted. The dimensionless mean concentration distribution as a function of dimensionless axial distance and time for different values of physical parameters is shown. The corresponding results for the case of 'pure convection' is also reported.
