Abstract (EN): The dissolution of a slightly soluble sphere buried in a packed bed of sand, through which water flows is considered in the present work with due consideration given to the processes of transverse and longitudinal dispersion. Numerical solution of the equations was undertaken to obtain point values of the Sherwood number, as a function of the Peclet and Schmidt numbers over a wide range of values of the relevant parameters. A correlation is proposed that describes accurately the dependence found numerically between these dimensionless parameters.
