Abstract

Ranges and flow rates of liquid weeping accompanied by bubble formation at a submerged single orifice were investigated experimentally.<BR>The liquid weeping rates were measured under the following conditions : orifice diameter (2-12 mm), plate thickness (1-10 mm) and chamber volume (50-28, 000 cm3).<BR>The liquid weeping rates increase with increasing orifice diameter (d) and decrease with increasing chamber volume (Vc). The effect of plate thickness on weeping rates is small. The ranges of d and Vc in which weeping occurred were determined and correlations of the ranges of gas flow rates with the weeping were proposed as a function of d, Vc, etc. It became clear that the maximum weeping rates and the gas velocity at the maximum weeping point were also correlated by d, Vc, etc.
