Abstract
This paper deals with the studies of cooling tower, operated with the contactless evaporative cooling technology. The authors developed the cooling tower with a three-flow liquid cooling system. The authors conducted the numerical studies of gas-liquid flow dynamics in the inclined-corrugated elements of checker filling unit that allows to give us an idea of two-phase flow structure, its movement throughout the checker filling, as well as to assess the influence of mode parameters on the efficiency of collecting the liquid drops and the range of stable operation of device. The most effective operation of this device is at the pressure drop of 100 Pa, while developing the average air flow rate in the element up to 3.2 m/s.
Highlights
Nowadays, the water resources in the world are under threat, thats why another problem is the pollution of these resources
In order to reduce the water consumption for industrial needs, the enterprises use the circulating-water supply system, which significantly reduces the amount of water consumption
Water is cooled in the cooling towers mainly by atmospheric air within the volume of the cooling tower filler unit, which consists of checker filling layers, with mainly the countercurrent movement of phases [1,2,3]
Summary
The water resources in the world are under threat, thats why another problem is the pollution of these resources. The usage of chemical agents is widespread i.e. adding of them into the water medium, causing the death of microorganisms This method has a number of disadvantages: one type of chemical agent destroys certain types of bacteria, but in order to destroy the others, it is necessary to use another type of chemical agent. The purchase of chemical agents is expensive, since it is required to purchase sufficiently large amounts of them, as well as adding of them into the liquid requires additional material and physical investments In this regard, it is necessary to develop the designs of filler units, considering all these requirements [8]
