An understanding of the behaviours of liquid holdup in upper section of cyclonic separator is required for proper design and prediction of operating envelope and pressure drop.

... Abstract Experiments for low liquid loading in two- and three-phase flows have been conducted at the SINTEF Multiphase Flow Laboratory in the Large Scale Loop. Low liquid loading means that the superficial liquid velocity is small compared to the superficial gas velocity; but the liquid holdup...

... Froude number equals unity, or the so-called accumulation point, where the liquid holdup starts to increase sharply with reducing gas flow rate. We developed an algorithm for computing the two points and performed a study to quantify the deviations between liquid flow rate and holdup at the critical...

We have explained how the removal of the liquid, when the gas flow is increased to inside the multiple holdup solution region, can be described by a steady state fully developed flow approximation.
