... ABSTRACT The present paper is focused on the development of an accurate 1D numerical model for pig motion in two-phase flow. The focus will be on the liquid slug that is accumulated in front of the pig, the so-called pig-generated slug. Under the assumption of a stratified flow, we first...

... Col (2) studied the behaviour of huge waves of churn flow for four different pipe diameters of 10, 20, 30, and 32 mm, while the superficial gas velocity (VSG) ranged from 0.8 to 6 m/s. production control flow regime prediction fluid dynamics production logging liquid slug cfd simulation...

... was equal to -510 Pa/m and the liquid hold-up was 57%. The long bubble velocity was 4.64 m/s, its length being 4.4 meters and the length of the liquid slug was 3.6 m. Different works were published on the numerical simulation of slug flow in milli-tubes and milli-channels. Recently, Valluri et al. (2008...
