Introduction. The development of the theory of synthesis of systems of intensive mass exchange processes at the expense of energy potentials of liquid or gas-liquid flows provides the realization of actual needs. Materials and methods. The paper analyzes the physical basis of methods and ways of intensification of processes in liquid and gas-liquid systems and phenomenological generalizations based on known laws of nature with mathematical formalization of relationships between geometric, kinematic and hydrodynamic parameters. Results and discussion. The study shows the possibility of synthesis of inertial fields due to the variable geometric parameters of pipelines, namely, the cross-sectional area, and due to the alternation of curvilinear and straight sections and trajectories of variable curvature. The generalized representation of the factor of intensification of mass exchange processes relates to force actions in the form of the consequences of pressure redistribution as a result of the redistribution of kinetic and potential energy potential. Possibilities of variations by values of force influences due to combinations of gravitational field and inertial fields of different orientation and frequency of effects have been shown, including with the possibility of reproduction of dynamic shocks in zones of change of signs of radii of curvature. Synthesis of inertial fields in such systems is achieved by such factors as variable flow velocity or change in flow direction. The combination of these two factors is more effective. Energy support of the intensification of mass exchange refers to the initial conditions of flow creation, and the overall positive result is ensured by accurate localization of processes. Conclusions. The factors of intensification of mass exchange processes are represented by the synthesis of inertial fields due to changes in the velocity and direction of the flow of the medium.
