... to account for the effect of gravity, which limits the film thickness for lower gas rates. Oil droplets are more effectively transported by the turbulence in the gas, so the liquid film on the pipe wall tends to have a lower aqueous fraction than the liquid layer in the bottom of the pipe. In the general...

... Turbulent Poiseuille flow of two immiscible liquid layers inside a rectangular channel has been performed adopting a Direct Numerical Simulation of wall bounded flow, coupled with the Phase Field Model (PFM). A thin liquid layer flows on top of a thick liquid layer, their thickness ratio is h 1/h 2 = 1/9...

... ABSTRACT This paper reports on an experiment aimed at obtaining detailed velocity fields in a wavy liquid layer in stratified air/water pipe flow. By combining Particle Image Velocimetry (PIV) with an interface detection technique, the velocity field is resolved from the pipe wall...

... ABSTRACT Experimental studies on the void distribution in the liquid layer in stratified wavy flows have been carried out in a 4-inch diameter pipe using a fast response X-ray tomography system. This work is concentrated on flows with high gas density, SF 6 up to 8 bara, under various near...
