原始语种摘要: Abstract(#br)Gas crossflow on a falling liquid film occurs in many practical cases in industries, particularly, in the downcomer of the APR1400, when accidents such as damage to the cold legs occur, hot steam crossflows over the vertical falling water film formed by the water impingement on the wall through a direct-vessel injection nozzle. Such crossflow may degrade the heat transfer ability of the liquid film. To investigate the film characteristics of downward flowing water, across which air was blowing horizontally, an experimental setup was designed and assembled. Experiments were conducted under different water flow rates (2, 3, 4, and 5 L/min) and different air velocities (0, 3.4, 4.9, 6.9, 8.4, and 9.8 m/s) to determine their effect on the film structure. A confocal chromatic...
