A MULTI-PHASE MODEL FOR PEDESTRIAN FLOW WITH STRATEGIC AND TACTIC COMPONENT
(AMER INST MATHEMATICAL SCIENCES-AIMS, 2014)
A new enrichment space for the treatment of discontinuous pressures in multi-fluid flows
(Wiley-BlackwellHoboken, 2012)
In this work, a new enrichment space to accommodate jumps in the pressure field at immersed interfaces in finite element formulations, is proposed. The new enrichment adds two degrees of freedom per element that can be ...
Comparison between staggered and collocated grids in the finite-volume method performance for single and multi-phase flows
(Pergamon-elsevier Science LtdOxfordInglaterra, 1999)
Three-dimensional, fully adaptive simulations of phase-field fluid models
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
We present an efficient numerical methodology for the 31) computation of incompressible multi-phase flows described by conservative phase-field models We focus here on the case of density matched fluids with different ...
Orifice plate meter field performance: formulation and validation in multiphase flow conditions
(Philadelphia, 2014-01-04)
The performance of orifice plates in real-time monitoring of oil, gas and water standard flow rates was
investigated. To this end, a multi-rate test was implemented in two production wells routed individually
to a test ...
Grid-tie three-phase inverter with active and reactive power flow control capability
(2013-01-01)
This paper proposes a methodology for the active and reactive power flow control, applied to three-phase inverter operating in grid-connected mode at low AC voltage. The converter's control technique is based on Linear ...
A two-phase solver for complex fluids: Studies of the Weissenberg effect
(Elsevier B.V., 2016-09-01)
In this work a new two-phase solver is presented and described, with a particular interest in the solution of highly elastic flows of viscoelastic fluids. The proposed code is based on a combination of classical Volume-of-Fluid ...
Power flow control in single-phase and three-phase grid-connected inverters using LMI, state-feedback linearization and D-stability
(2013-12-17)
This paper proposes a methodology for the active and reactive power flow controls, applied at singlephase and three-phase inverters operating in grid-connected mode at low voltage. The converter's control technique is based ...
Thermal hydraulics simulation of the RD-14M steam generator facility
(Elsevier Science Ltd, 2017-07)
A full three-dimensional Computational Fluid Dynamics simulation of the secondary circuit of a steam generator test facility was carried out. The multiphase flow was studied using the two-fluids Eulerian model. A constant ...
