Modelling multiphase flow with an Eulerian approach, Von Karman Institute Lecture Series-Industrial Two-Phase Flow
CFD, May 23-27, von Karman Institute, Belgium.
The error bars on the test probe data indicate large variations between consecutive samples at the same flow conditions, indicating a dynamic two-phase flow
2002 ) have indicated that separation of vapor-liquid two-phase flow
has great applications in the field of heat exchangers.
The topology of the two-phase flow
is represented by two properties; VOF represents the liquid volume fraction and LS is the shortest distance from the interface, positive within the liquid, negative outside and zero on the interface.
Orkiszewski firstly applied the concept of bubble lift speed which reflects the two-phase flow
mechanism to the pressure drop calculation of two-phase flow
in vertical oil and gas wells.
In addition, the single-phase flow merges faster than the two-phase flow
In the processes where air flows in counter-current or co-current to the film flow, problem is stated as a two-phase flow
, and studied in many experimental and theoretical studies .
Oil-in-water two-phase flow
widely exists in petroleum industry such as crude oil production and transportation.
Different experimental researches for air-water two-phase flow
in a 90[degrees] bend have been carried out to measure different flow properties and system conditions, and compared with empirical correlations (Silberman, 1960; Kim et al.

The VOF process uses the Navier Stokes equations to replicate the two-phase flow
