Heat and mass transfer in unit of cooling tower filler with advanced gas-liquid contact surface

Abstract

On a global scale, many cooling towers and contact elements occur in a variety of types. In this paper, a new design of the tower with the technology of contactless evaporation cooling has been presented. Experimental studies of the efficiency of heat and mass transfer processes in the inclined-corrugated element with the advanced gas-liquid contact surface as metal mesh were performed. Results of the change in the efficiency of heat and mass transfer processes from various gas velocity and the ratio of mass flow ratio of liquid and gas phases were reported. Comparative analysis of the influence of specific surface of phase contact on the efficiency of cooling circulating water was carried out. It was found that the use of additional contact surface of the phases allows increasing the efficiency of thermal and mass transfer on average of 44.8% and 54.2%, respectively. The mean-flow air velocity without entrainment of liquid from the apparatus reaches 2.7 m/s.

Experimental study of heat transfer in tube-type radiator of hybrid cooling tower

“…More detailed descriptions of the experimental setup with the main design features are given in papers [11][12][13]. Various instruments were used to measure and control the parameters during the experiments, designated in the diagram (figure 1) as "T, F, φ," the characteristics given in table 1.…”

Spatial effect of a vertical multi-faceted rib on thermal performance and flow characteristics in a square channel

“…Even though the cooling tower fill structure can be quite similar to an internal flow with baffles and ribs, the literature is almost non-existent, particularly in the scope of internal flow with obstacles or even in the cooling tower studies. There are various film-type cooling tower fill designs available, consisting of different geometries of obstacles such as corrugated, 3 wave surface, straight, and zig-zag type fill. 4 Each has a varying effect on fluid film rate and airflow.…”

Experimental study on thermal performance in three-flow cooling tower

“…So far, a novel fill pack has been developed, consisting of inclined-corrugated contact elements [26]. A previous study of the dynamics of liquid and gas flows [27,28] showed the possibility of uniform distribution of liquid along the cooling tower's cross-sectional area.…”
