The motion of a two-phase gas-liquid jet with small-size bubbles in an ozonizer has been calculated. The mathematical model used in the calculations, unlike the model of interpenetrating continuums for a two-phase medium, does not contain small parameters for derivatives. By virtue of the consideration of the medium compressibility and the dependence of the density on the concentration of bubbles, this model automatically takes into account the processes causing free convection in the gravity field in the presence of the heterogeneous concentration of bubbles. Parametric studies based on the proposed model have been conducted. The efficiency of this approach has been shown. The acceleration of the floating of a gas jet due to its involvement in the motion of the carrier medium has been confirmed. The parameters of the process of dissolution of ozone in the contact tank have been determined, the efficiency of the location of dispersants has been evaluated.
