Web2 feb. 2011 · The boundary condition of the film thickness δ, i.e., δ = 0 at the start of condensation, is used in the Nusselt analysis. However, many fine droplets are observed to flow onto the top wall of the tube, so that the film thickness is not zero at the tube top. WebPhysics of Fluids 2012. In this paper we report measurements of the heat flux in a slightly tilted channel (angle less than 45°), filled with water, that connects two chambers: the hot in the lower part and the cold on the top. We show that different regimes develop depending on the angle and the applied power.
