“…The effect of air velocity on the cooling efficiency of the hybrid cooling tower is due to the change in the average temperature of the coolant liquid due to turbulence of the two-phase gas-liquid flow in the cooling tower fill. However, an excessive increase in the average air velocity can lead to the breakdown of liquid droplets and their further entrainment from the device [12]. The efficiency of the heat transfer process through the wall of the finned radiator in the hybrid cooling tower is described by the following regularities: when the fill operates in the film mode, the change in efficiency with an increase in the average air velocity does not exceed 5.4%.…”

“…Earlier studies [11] showed that the main thermal resistance is concentrated during heat transfer from the wetting liquid to the outer wall of the radiator tubes. To intensify the processes of heat and mass transfer inside the cooling tower, the radiator tubes are made with transverse finning, which also increases the overall surface of heat transfer [12].…”

Hybrid cooling towers are a new type of equipment that can be used in cooling water circuits. In this work, a hybrid cooling tower is developed, in which inclined corrugated plates are used as a fill, and the circulating liquid flows through an internal tubular radiator, the finned surface of which is continuously washed by the coolant water. The purpose of the work is to perform an experimental evaluation of the cooling efficiency of the developed hybrid system used for circulating water cooling. It was obtained that at the wetting density of the coolant water equal to 28.3 m3/(m2·h) and the mass flow rate of the circulating water in the tubular radiator of 0.0135 kg/s, the cooling efficiency of the developed cooling tower can reach 38.6%.
