Abstract

A two-dimensional model involving both radial and axial mixing under the condition of steady tracer injection from a point source is presented. The model parameters are estimated by the optimal method of nonlinear programming

using the two dimensional RTD experimental data obtained in a. one meter diameter packed column. Dimensionless equations for the evaluation of axial and radial Peclet numbers are regressed.
