Experimental study of turbulence effect on re-aeration

It is proposed that the oxygen fluxes caused by molecular and turbulent dif fusion should be studied separately. Based on turbulent re-aeration experim ents, a quantitative relationship between interfacial mass transfer coeffic ient and interfacial kinetic energy is developed. It not only simplifies th e formula of re-aeration coefficient, but also gives fully consideration to the effect of interfacial kinetic energy on re-aeration. It is of great im portance for predicting dissolved oxygen distribution and studying the effe ct of hydrodynamic characteristics an turbulent re-aeration processes.
