Subject. The article is devoted to the study of the impact of discrete-pulse energy input on hydrodynamic processes in liquid water technological environments. Purpose. Determination of specific properties and related phenomena occurring in water processed in heat and mass exchange devices with discrete-pulse energy input. Methods. The technological process of the influence of discrete-pulse energy input is described by the Rayleigh equation, which determines the dynamics of a spherical bubble in a liquid volume taking into account the radius of the bubble, pressure, and viscosity. The energy distributed in the working volume is concentrated in local discrete points of the system and is further pulsed to achieve the required thermophysical effects. Results. Radical transformation reactions with participation of chemically active gases occur in cavitation cavity, as a result of which after collapse of cavitation bubble products of radical decomposition of molecules pass into solution, which leads to accumulation of molecular oxygen, hydrogen peroxide and other compounds in water. At the same time, the structure of water changes with the formation of free hydrogen bonds, which causes its increased activity and reactivity. In aqueous systems, activation consists in changing the degree of uniformity of distribution of impurities in the system volume, aggregation and dispersion, as well as in changing their active state. Scope of the results. The method described in the article will allow intensifying technological processes in comparison with the classical method of stirring using conventional stirring devices. The high reaction rate indicates that the reactions take place in the zone of bubble collapse. This is a positive technological moment.
