✦ Synopsis

Expertmental correlations for the parameters of the plug-flow model with Imposed longltuchnal dls-pers~on, I e the longtudmal dlsperslon coefficient and the real mass-transfer coefficient, have been derived Assummg that the dispersion takes place only on the gas side, concentration profiles of the component being transferred have been measured From the expenmental data correlations were derived allowmg to compute the gas-phase Peclet number and the real mass transfer coefficient The correIahons are then used In the further analysis of the influence of longmuimal dispersion on mass transfer m packed columns

## Abstract Experimental data on flow pattern transitions, pressure drop, and flow characteristics for cocurrent gas–liquid flow through packed columns in microgravity is analyzed. The pulse flow regime exists over a wider range of gas and liquid flow rates under microgravity conditions. Furthermor
