Abstract: Axial mixing in open and packed columns with and without the application of pulsation is studied. It is found that the dispersion coefficient increases with increase in flow rate, amplitude of pulsation in both open and packed columns, and with frequency it increases to some extent and then decreases. In packed columns the dispersion coefficient is found to increase with increasing particle diameter. The dispersion coefficient is found to be much higher with pulsation than without pulsation in both open and packed columns. The data in the present study without pulsation follow pure convection model for open column and are found to be in good agreement with Bischoff correlation for packed column. Correlations are developed for the axial dispersion coefficient in open and packed columns based on modified NpeNRe numbers, considering the effects of all the parameters studied in the present work.
