Abstract

Heat transfer processes in contact heat exchangers are largely determined by the hydrodynamic regimes of the apparatus. The aim of the research is to determine the optimal quantities and sizes of tangential swirlers of the vortex apparatus, which ensure the highest efficiency of its operation. The paper presents the data obtained when studying various designs of gas flow swirlers of a vortex apparatus and their effect on the structure of swirling flows by virtual modeling of trajectories by the SolidWorks software in the Flow Simulation application. A comparative analysis of these parameters is carried out for different values ​​of the swirl coefficient (dimensions of the swirler slots) and the number of tangential swirlers of the gas flow. As a result, the optimal parameters of tangential swirlers were established for effective design of the swirling flow process.
