Flow regime development analysis in adiabatic upward two-phase flow in a vertical annulus
Elsevier (2011)In this work radial and axial flow regime development in adiabatic upward air–water two-phase flow in a vertical annulus has been investigated. Local flow regimes have been identified using conductivity probes and neural ... -
Flow regime transition criteria for two-phase flow in a vertical annulus
Elsevier (2011)In this work, a new flow regime transition model is proposed for two-phase flows in a vertical annulus. Following previous works, the flow regimes considered are bubbly (B), slug (S) or cap-slug (CS), churn (C) and annular ... -
Intrusive sensors for two-phase flow measurements
Universitat Jaume I (2022-11-18)Electrical impedance techniques have been investigated and used for the measurement of two-phase flows, both theoretically and experimentally. A proprietary design of intrusive probes composed of four sensors has been used ... -
Local flow regime analysis in vertical co-current downward two-phase flow
Elsevier (2013)In this work, both global and local flow regimes in two-phase downward flow in a 50.8 mm internal diameter pipe in adiabatic conditions have been identified. The bubble chord length distributions measured simultaneously ... -
Numerical investigation of models for drag, lift, wall lubrication and turbulent dispersion forces for the simulation of gas-liquid two-phase flow
Elsevier (2015-06)In order to qualify CFD codes for accurate numerical predictions of transient evolution of flow regimes in a vertical gas–liquid two-phase flow in a pipe, suitable closure models (inter-phase forces) for the momentum ... -
On the use of area-averaged void fraction and local bubble chord length entropies as two- phase flow regime indicators
Springer Verlag (2010)In this work, the use of the area-averaged void fraction and bubble chord length entropies is introduced as flow regime indicators in two-phase flow systems. The entropy provides quantitative information about the disorder ...
