Abstract
Effect of baffle on a tray under oscillating conditions has been examined experimentally. To reduce the degree of liquid mixing and liquid channeling under oscillating conditions, it is necessary to install the baffles on tray. Experiments were conducted with the air-water system, ft was found that the pressure drop change can be expressed as a sinusoidal function and the period coincides with tray oscillation. The degree of liquid mixing decreases when the baffles are installed on tray and it also decreases with the increase of liquid flow rate. The pressure drop increases with the installation of baffle on tray. The suitable baffle number on tray is from 4 to 8 and in this region, the degree of liquid mixing reaches minimum and the liquid holdup takes a maximum value. @KEYWORDS: Tray, Oscillating, Liquid mixing, Baffle, Pressure drop, Liquid holdup.
