Mass transport in contaminated flows (Q1370837)

We consider the effect of the presence of a monomolecular film on the free water surface of infinite horizontal extent. The expressions for the velocity field and the mass transport velocity are presented for the motion induced by a surface progressive wave in the regions of the free surface and the bottom boundary layers, and in the interior region. The bottom boundary layer is assumed to be fully turbulent. Also the wave damping coefficient is calculated. It is shown that the vorticity flux across the bottom boundary of the free surface boundary layer varies with the film compression modulus and the solubility.
