✦ Synopsis

The one-dimensional dispersion model under the assumption that the fluid is completely mixed in the radial direction is generally used to describe turbulent mixing in apparatus with axial flow. With increasing apparatus diameter, however, this assumption becomes less correct and it becomes necessary to take radial mixing into account. In the following example a mathematical solution of the two-dimensional model is developed and applied to describe the turbulent mixing in a sieve-tray extraction column.
