Abstract The 1D Two-Fluid model is based on an area average process of the time and
phase averaged Two-Fluid conservation equations to render the model tractable for …

We present experimental and numerical results for by-pass pigging under low-pressure

We show that the one-dimensional (1D) two-fluid model (TFM) for stratified flow in channels
and pipes (in its incompressible, isothermal form) satisfies an energy conservation equation …

Multiphase flows are described by the multiphase Navier-Stokes equations. Numerically
solving these equations is computationally expensive, and performing many simulations for …

The pressure‐free two‐fluid model (PFTFM) is a recent reformulation of the one‐
