| Abstract: | The reaeration progress for turbulent water is studied by the flume reaeration experiment and the interfacial mass transfer coefficients are obtained by employing the oxygen-flux theory.The expression of the interfacial mass transfer coefficient related with velocity and kinetic energy is developed by using the numerical model to simulate the turbulence characteristics of the flow field.The examination with the experimental data of different cases shows the validation of the theory. |
