Simulation Results of the Evaluation of the Stresses Acting on a Thin Shear Driven Water Film

Results of the investigation of instantaneous and time-averaged stresses in a film flow with a thin shear-driven water film below an outer turbulent free flow by using Direct Numerical Simulation (DNS). The film Reynolds number based on the average film velocity and the average film thickness is 50 and the gas Reynolds number based on the average boundary layer thickness and the average gas flow velocity is 54,000.
