Modelling of turbulent flow in a radial reactor with fixed bed

The data of the computation of turbulent flow in the CF-pi and CP-pi configurations of the radial reactor with a fixed bed are presented. The Reynolds motion equations have been solved jointly with the k-E > turbulence model. To couple the parameters of flows at the interface free part-fixed bed the classical continuity equations were used. The computational data are obtained for the averaged and turbulent characteristics, and it is shown that the flow in the fixed bed causes the generation of the turbulence kinetic energy and its dissipation rate; the flow in the CF-pi configuration is distributed more uniformly as compared to the CP-pi configuration of the radial reactor. Computed data are compared with the experimental ones.
