Pressure drop through sudden expansions are numerically investigated for two-phase flow
of oil/water emulsions. Two-phase computational fluid dynamics (CFD) calculations, using
Eulerian–Eulerian model are employed to calculate the velocity profiles and pressure drop
across sudden expansion. Axial pressure drops have been determined by extrapolating the
computed axial pressure profiles in the regions of fully developed pipe flow upstream and
downstream of the pipe expansion, to the transitional cross section. The oil concentration is …

Purpose–The purpose of this paper is to compute the pressure drop through sudden
expansions and contractions for two‐phase flow of oil/water emulsions.
Design/methodology/approach–Two‐phase computational fluid dynamics (CFD)
calculations, using Eulerian–Eulerian model, are employed to calculate the velocity profiles
and pressure drops across sudden expansions and contractions. The pressure losses are
determined by extrapolating the computed pressure profiles upstream and downstream of …
