文摘This paper presents entrainment mechanism, and transported and diffusioncharacteristics at the point of entry of submerged jet. The profiles of both velocity andconcentration within the air-water mixing layer were theoretically deduced. And the comparisonsbetween theoretical values and measured data were made. Results show that the velocity profilewithin the air-water mixing layer exhibits a form of error function. The concentrations of airentrainment in the internal and external regions of air-water mixing layer correspond to Gaussiandistribution.
