...). Dispersion viscosities derived from pressure drop measurements increased with higher dispersed phase fraction. However, the relative increase in viscosity was considerably less for the condensate – MEG system when compared with the model system. For all systems, a peak value of the viscosity was reached...

... 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...
