Abstract
Stability analysis of complex two-phase slug flow is carried out by using OpenFOAM (CFD) open-source codes. Flow in symmetrical pipe geometry is simulated using isoAdvector (geometric algorithm) which uses VOF method to track interactions of two fluids at the interface. Grid independence is established by choosing liquid hold-up as grid sensitivity parameter. During the two-phase flow through horizontal pipes standing waves and hydraulic jumps have identical characteristics. Slugs within pipe are observed to be the sudden pressure transition or high energy zone. Due to these characteristics, a situation of hydraulic jump within and around slugs arises. Further, the mechanism of shedding and picking rate of water at slug front and alteration in length of travelling slugs are analysed.
