Abstract

Based on the distribution features of 3D flow and temperature fields in the tower under crosswind, a three-zone synergistic optimization pattern is established for the water-spraying zone, fillings zone and rain zone: elliptical partition water distribution, elliptical non-equidistant fillings layout, and non-centrosymmetric dry-wet hybrid rain zone. The numerical simulation method is employed to investigate the effect of the three-zone synergistic pattern under crosswind on the cooling tower thermal and resistance performance. The three-zone synergistic pattern, according to the results, optimizes the distribution of the multi-physical fields inside the cooling tower, and greatly improves the thermal and resistance performance of the tower at distinct crosswind speeds. Taking a typical wind speed v = 5 m/s under the design condition (the standard operating condition set during the design phase) as an example, the water temperature drop, cooling efficiency and ventilation of the cooling tower with the three-zone synergistic pattern under crosswind increase by 0.72 °C, 4.19 % and 335.74 kg/s, respectively, compared with the conventional cooling tower. This work can provide important references for the thermal design and technological transformation of large wet cooling towers under crosswind.

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
