Kurzbeschreibung (Abstract)
Abstract In this work a two-step model to investigate a thin liquid film sheared by a turbulent gas flow is presented. In a first step, a direct numerical simulation of the gas phase is conducted. The turbulent shear stress at the lower wall is stored and used as a boundary condition for the long-wave evolution of the liquid film, which is calculated in a second step. Results show that the turbulent shear stress fluctuations have to be considered when evaluating turbulent-two-phase channel flows.
