title: Effect of hydrodynamic characteristics on reaeration process.
abstract: The equilibrium-perturb technique was used in the flume reaeration experiment. The interfacial mass transfer coefficients of DO were obtained by implementation of the oxygen-flux theory in the study. The turbulence characteristics of the flow field were investigated by numerical simulation approach. The expression of interfacial mass transfer coefficient related with velocity and turbulence kinetic energy was built. Examination with the experimental datum of different cases showed the validation of the expression.
