Abstract
The flow dynamics and heat transfer characteristics of the condensate film on a vertical wall is analysed by solving the time-dependent Navier-Stokes and the energy equation as well as the Poisson equation for the pressure with finite difference schemes and non-periodic boundary conditions. The simulation shows the evolution of the condensate film from the leading edge until 0.6 m by the low frequency surface fluctuation upstream of the line of wave-inception. Downwards, the time-averaged film thickness is decreasing with the flowing of big short waves, which are merging afterwards into individual long waves. The strong influence of the wave on the flow is shown by the pressure and vorticity field.
