Research on heat and mass transfer characteristics of a counterflow wet cooling tower using a new type of straight wave packing

In this paper, a new type of straight wave packing is developed for the purpose of improving the heat and mass transfer characteristics of counterflow wet cooling towers. Experimental studies and numerical simulations are carried out to explore the effects of inlet air velocity, water drenching density, gas-liquid ratio and packing height on the heat and mass transfer characteristics of cooling towers. According to research, the novel packing's cooling efficiency increased by 14.4% when compared to the conventional straight wave packing. This is a more substantial effect, and it offers a new plan for the cooling tower's heat transfer that can direct engineering practice. Combined with the analysis of the actual tower operating conditions, it is found that the higher the height of the packing, the easier it is to meet the cooling task, and the smaller the reasonable gas-liquid ratio and air volume required, the maximum air volume can be saved by 30%.
