A CFD-DEM solver to model bubbly flow. Part II: Critical validation in upward vertical pipes including axial evolution

Peña-Monferrer, Carlos; Monrós-Andreu, Guillem; Chiva Vicent, Sergio; Martinez-Cuenca, R.; Muñoz-Cobo, J. L. (Elsevier, 2018)

[EN] In the computational modeling of two-phase flow, many uncertainties are usually faced in simulations and validations with experiments. This has traditionally made it difficult to provide a general method to predict ...
An Eulerian-Lagrangian open source solver for bubbly flow in vertical pipes

Peña Monferrer, Carlos; Muñoz-Cobo González, José Luís; Monrós Andreu, G.; Martinez Cuenca, R.; Chiva Vicent, Sergio (Sociedad Nuclear Española, 2014-10)

Air-water two-phase flow is present in natural and industrial processes of different nature as nuclear reactors. An accurate local prediction of the boiling flow could support safety and operation analyses of nuclear ...
CFD modelling and validation of upward bubbly flow in an adiabatic vertical pipe using the quadrature method of moments

Peña Monferrer, Carlos; Passalacqua, Alberto; Chiva Vicent, Sergio; Muñoz-Cobo González, José Luís (Elsevier, 2016-05)

[EN] An Eulerian-Eulerian approach was investigated to model adiabatic bubbly flow with CFD techniques. In the framework of the OpenFOAM (R) software, a two-fluid model solver was modified to include a population balance ...
CFD Turbulence Study of PWR Spacer-Grids in a Rod Bundle

Peña Monferrer, Carlos; Muñoz-Cobo González, José Luís; Chiva Vicent, Sergio (Hindawi Publishing Corporation, 2014)

Nuclear fuel bundles include spacers essentially for mechanical stability and to influence the flow dynamics and heat transfer phenomena along the fuel rods. This work presents the analysis of the turbulence effects of a ...
Computational fluid dynamics multiscale modelling of bubbly flow. A critical study and new developments on volume of fluid, discrete element and two-fluid methods

Peña Monferrer, Carlos (Universitat Politècnica de València, 2017-11-06)

The study and modelling of two-phase flow, even the simplest ones such as the bubbly flow, remains a challenge that requires exploring the physical phenomena from different spatial and temporal resolution levels. CFD ...
Development and validation of a one-dimensional solver in a CFD platform for boiling flows in bubbly regimes

Gomez-Zarzuela-Quel, Consuelo; Chiva Vicent, Sergio; Peña-Monferrer, Carlos; Miró Herrero, Rafael (Elsevier, 2021-04)

[EN] This paper presents a new one-dimensional solver for two-phase flow simulations where boiling is involved. The solver has been implemented within the OpenFOAM® platform. The basic formulation follows the Eulerian description ...
Estudio del flujo bifásico aire-líquido en tuberías verticales: Base de datos experimental para la validación de programas CFD

Monrós, G.; Martínez, R.; Torro, S.; Chiva Vicent, Sergio; Peña Monferrer, Carlos; Muñoz-Cobo González, José Luís (Sociedad Nuclear Española, 2014-10)

El estudio del comportamiento del flujo multifásico y su modelado ha sufrido un gran cambio con la introducción de los programas CFD, y el avance en los sistemas de medida. La resolución temporal y espacial de los ...
Participation in the NEA/OECD MATiS-H Benchmark exercise. Study of spacer grids in a rod bundle

Peña Monferrer, Carlos; Chiva Vicent, Sergio; Muñoz-Cobo González, José Luís; Vela, E.; Pelayo, F. (Sociedad Nuclear Española, 2012-10)

Nuclear fuel bundles contain spacers essentially for mechanical stability and to influence the flow dynamic and heat transfer phenomena along the fuel rods. This work presents the analysis of the turbulence effects of a ...
