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 of RELAP5/MOD3 predictin

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 split-type and swirl-type spa

This paper describes the work done in collaboration with the Spanish Nuclear Regulatory Commission (CSN), and it is related with scaling analysis in multiphase systems like pressure water reactors (PWR) during accidental conditions. A method was deve

The study of flow configuration and regime transitions in a vertical pipe is of primary interest for the understanding of the fundamentals of two-phase flow dynamics. Also, it is useful for the calibration of both interfacial forces and population ba

A new method to compute the dispersed phase in a Lagrangian framework is shown in this contribution for computing incompressible bubbly flows. Each bubble is divided dynamically in equivolumetric elements and tracked into the Eulerian mesh for an app

In this paper, a time dependent model for studying BWR in phase instabilities in the nonlinear regime is developed. This model is based on solving the mass energy and momentum conservation equations, for the single phase region and for both phases in

Annular two-phase flow has been vastly investigated due to its large and deep involvement in a large amount of industrial processes, for instance, petroleum, chemical, civil and nuclear industries, and particularly in boiling and condensing heat tran

Submerged gaseous jets may have an outstanding relevance in many industrial processes, but are particularly relevant in severe nuclear accident scenarios, like the one happened at the Fukushima Daiichi NPP several years ago. Even though pool scrubbin
