✦ Synopsis

Backmixing as a function of the liquid flow rate and the stirring speed has been determined in a rotating disk contactor. It is shown that the degree of backmixing in the region investigated is not inhuenced by the liquid flow rate. It appears that the backmixing coefficient is equal to the contribution to the apparent axial diffusion, which is due to the stirring.

For homogeneous liquid phase operation the residence time distribution in two small rotating disk columns has been investigated and interpreted by means of a diffusion model. P&let numbers, CL/9, ranging from 0.6 to 31 were found. It is shown that the apparent axial diffusivity may be considered as

## Abstract A correlation for the estimation of dispersed phase axial mixing coefficients in terms of all the operating and fundamental variables was established. The proposed correlations are found to be a good representation of the present data (260 data points) obtained using four liquid‐liquid
