Re-aeration in skimming flow over stepped chutes: two-dimensional CFD modeling and empirical equations

ABSTRACT Flows in stepped chutes and spillways are highly turbulent and have the potential of absorbing and desorbing volatile compounds. The present work aimed to model the interfacial mass transfer in skimming flows using the two-resistance model and the advection-diffusion equation. The simulatio...
