Abstract
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.
