Study of the Flow Structure Stability in a Multi Vortex Contact Device

In this scientific paper, the authors studied the dependence of the change in the relative height of vortex formation on the dimension of the Field tube structure by means of numerical simulation, as well as the dependence of the change in the relative height of vortex formation on the fluid medium flow rate. Making several holes in the base contributes to the appearance of numerous uniform vortices in the air or water environment, which affect the intensity of heat transfer. Numerical simulation in the ANSYS Fluent software program was carried out to study this device. Analysis of the experimental data obtained showed that an increase in the angular rate leads to an increase in the height of the vortices. The relative height of the vortices practically does not depend on their diameter.
