Axial dispersion characteristics in the liquid phase have been determined for three selected types of static mixers using the impulse response technique in a vertical tubular contactor for single phase (water) and two phase (water-air, cocurrent flow arrangement) systems. The character of the measured dependences for individual types of static mixers has been found different and also corresponding values of axial dispersion have been found significant. From the stand point of axial dispersion the behaviour of the static mixer under the two phase flow has been found different from its behaviour in the single phase flow system.
