Experimental study on interfacial mass transfer coefficient of turbulent water
摘要
Abstract
Based on turbulent diffusion theory and the mechanism of liquid-gas interfacial mass transfer,a conceptual model of turbulent re-aeration process is proposed.The oxygen fluxes caused by molecular diffusion and turbulent diffusion are studied separately.According to the experimental data and theoretical analyses,the interfacial mass transfer coefficients of quiescent water and turbulent water with different turbulence are obtained.The relationship between interfacial mass transfer coefficient and interfacial ki-netic energy is established.关键词
