“…At industrial and energy enterprises and branches of technology, the task of intensifying the heat transfer process and creating highly efficient heat exchangers is very relevant. The efficiency of each stage of electricity production is discussed and ways to improve the efficiency of heat production are proposed [1][2][3][4][5][6][7]. It's known that at the transport enterprises of thermal power engineering and in many industrial production processes, processes are responsible for heat consumption due to the movement of the coolant in the form of hot water through pipelines that are limited by parameters and configuration.…”

The paper discusses the results of experimental studies of the influence of the degree of inhomogeneity of a liquid flow on the dynamics of heat and mass transfer processes under pulsed impacts. High-voltage electric discharges in a liquid medium were used as impulse actions, through which an electro-hydraulic effect is realized, accompanied by the appearance of shock waves. The dynamics ofthe occurring nonlinear, rapidly changing heat and mass transfer processes at high hydraulic pressures cannot be described using differential equations. The simulation was carried out on the basis of the method of group consideration of arguments, the advantage of which is the construction of polynomial dependencies using a small amount of experimental data. The results of constructing polynomial dependences made it possible to reveal the synergistic effect of the influence of flow parameters on the dynamics of the impulse pressure amplitude and the intensity of heat transfer.
