Numerical Simulation of the Effect of the Uneven Wall on the Liquid Film Flow

Article Preview

Abstract:

Two-dimensional models of inclined flat and corrugated walls are established based on VOF method to numerically simulate the flow characteristics of liquid film. The impact of wall structures on the wave profile of the film is studied. The results indicate that the wall structure plays an important role on the liquid film, there are vortexes generated on the trough of wavy wall, the vortex has the "rolling" effect in machinery, which reduces the viscous resistance. and continuous film is easier to form on the wall whose corrugated size is smaller.
