The efficiency of heat and mass transfer and mixing equipment is largely determined by the technological and geometric characteristics of contact devices. An important direction for accelerating heat and mass transfer processes is the creation of zones of enhanced mixing within the equipment, achieved through the introduction of intensive swirling flows. A vortex-type contact device has been developed for heat and mass transfer apparatus operating in a gas-liquid system, where phase interaction occurs in a swirling flow. The aim of the study is to determine the hydrodynamic characteristics of the developed vortex-type contact device under various operating conditions, with simultaneous changes in the resistance coefficient of the orifices and the swirl parameters of the flow. The paper presents the results of a study of the hydrodynamic characteristics of the vortex-type contact device for intensifying heat and mass transfer processes. Experimental studies were conducted on a laboratory setup using an air-water system. During the study, the effect of changes in the aerodynamic resistance coefficient of the orifices (ξ₀), the relative phase flow rate (Lm/Gm), and the gas swirl level on the liquid movement parameters - its velocity inside the nozzles and the thickness of the resulting film -was analyzed. The obtained data indicate that the key factors determining the hydrodynamics in the separator orifices are the degree of gas jet swirl, the initial gas velocity, and the resistance of the orifices. A direct correlation was found between the liquid feed rate and the resistance coefficient: an increase in ξ₀ leads to an increase in energy losses in the range of 85-95%. The range of stable operation of the vortex-type contact device was determined, with the film thickness ranging from 0.46 to 0.6 mm. At a ratio of Lm/Gm > 3, the increase in droplet carryover is significant, making the operating mode impractical. Additionally, it was established that intensification of flow swirl always increases the liquid velocity in the separator orifices, regardless of the specific phase load level (Lm/Gm). The obtained results enable the improvement of heat and mass transfer equipment designs.
