摘要: Abstract The purpose of this study is to determine the influence face velocity distribution on thermal performance a steam-electric power plant air-cooled condenser (ACC), and explore characteristics favorable (FFVD). experimental an A-frame cell chosen from widely used ACCs showed that tends increase in direction tube-side steam-condensate flow. In order investigate other type distributions, on-site wind tunnel with seven same size finned-tubes tied into ACC's steam vacuum system was constructed, distributions were experimentally studied. It found FFVD exhibits opposite measured cell. Adjusting towards through air deflectors improved test specimen by as much 6%. Based results, V-frame ACC proposed. numerical verified primary characteristic FFVD. This provides valuable guide for enhancement ACCs, adjust
