A CFD-DEM solver to model bubbly flow. Part I: Model development and assessment in upward vertical pipes
Peña Monferrer, Carlos; Monrós Andreu, Guillem; chiva, sergio; Martinez Cuenca, Raul; Muñoz-Cobo, Jose-Luis Elsevier (2018-02-02)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 the ... -
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, sergio; Martinez Cuenca, Raul; Muñoz-Cobo, Jose-Luis Elsevier (2018-02-23)In the computational modeling of two-phase flow, many uncertainties are usually faced in simulations and validations with experiments.

CFD modelling and validation of upward bubbly flow in an adiabatic vertical pipe using the quadrature method of moments
Peña Monferrer, Carlos; Passalacqua, A.; chiva, sergio; Muñoz-Cobo, Jose-Luis Elsevier (2016)An Eulerian–Eulerian approach was investigated to model adiabatic bubbly flow with CFD techniques. In the framework of the OpenFOAM® software, a two-fluid model solver was modified to include a population balance equation, ... -
CFD Turbulence Study of PWR Spacer-Grids in a Rod Bundle
Peña Monferrer, Carlos; Muñoz-Cobo, Jose-Luis; chiva, sergio Hindawi Publishing Corporation (2014-06)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 ... -
Development and validation of a one-dimensional solver in a CFD platform for boiling flows in bubbly regimes
Gómez Zarzuela, C.; Peña Monferrer, Carlos; chiva, sergio; Miró, R. Elsevier (2021)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 ... -
On the One-Dimensional Modeling of Vertical Upward Bubbly Flow
Peña Monferrer, Carlos; Gómez Zarzuela, C.; chiva, sergio; Miró, R.; Verdú, Gumersindo; Muñoz-Cobo, Jose-Luis Hindawi Publishing Corporation (2018)The one-dimensional two-fluid model approach has been traditionally used in thermal-hydraulics codes for the analysis of transients and accidents in water–cooled nuclear power plants. This paper investigates the performance ...
