CFD studies and experimental validation of the convective heat transfer coefficient in non-fully developed flows applied to conventional geometries used in particle accelerators
(Joint Accelerator Conferences Website (JACoW), 2023)
Conference report
Open AccessIn the field of Particle Accelerators engineering, the design of the cooling channels of its components has been extensively based on experimental correlations for the calculation of convective heat transfer coefficients. ... -
Effect of biofilm formation on the aggregation of microplastics in upper-ocean turbulence
(2023)
Conference report
Open AccessThe impact of biofilm formation on marine microplastics in the upper layers of the ocean has been investigated using direct numerical simulations with an Eulerian-Lagrangian point-particle approach. The influence of biofilm ... -
Suitability of immersed-boundary methods for high-fidelity computational aeroacoustics
(2023)
Conference report
Open AccessThis work presents a preliminary assessment of the suitability of the immersed boundary method (IBM) for high-fidelity direct sound computations. A ghost-cell IBM is implemented in conjunction with a recently developed ... -
Rotating waves arising from the instability of magnetized spherical Couette flows
(2022)
Conference lecture
Open AccessRotating waves of various azimuthal wavenumbers appear in magnetised spherical Couette flows in time-dependent states. The criteria for the flow to enter a time-dependent state are determined by the values of Reynolds and ... -

Diagnostics of a hydraulic turbine failure
(2022)
Conference report
Open AccessThis paper presents the failure analysis and diagnostic of a hydraulic turbine. Shortly after a maintenance revision the thrust bearing of the turbine was destroyed when the turbine was put into operation. The damaged ... -
Direct numerical simulation of wall-bounded turbulence at high-pressure transcritical conditions
(Springer Nature, 2022)
Conference report
Restricted access - publisher's policySupercritical fluids are commonly utilized in energy conversion and propulsion applications due to the higher power and efficiencies they provide. Their increased performance is connected to the thermophysical properties ... -
Characterization of the fluid damping in simplified models of pump-turbines and high head Francis runners
(IOP Publishing, 2022)
Conference report
Open AccessIn order to satisfy the power demand in the electrical grid, hydraulic turbine units frequently work under off-design operation conditions and pass through transient events. These operation conditions can lead to high ... -
Modeling a high temperature PEM fuel cell focusing on its thermal behavior
(2017)
Conference report
Open AccessThe aim of this work is to develop a Computational Fluids Dynamics model using COMSOL Multiphysics, focusing on the thermal behaviour of a real HT-PEMFC . Energy management is the main concern as a better refrigeration ... -
Hybridization in Kaplan turbines. Wear and tear assessment
(IOP Publishing, 2022)
Conference report
Open AccessIn the current energy market, hydraulic turbines are increasingly demanded to work in Frequency containment reserve (FCR) mode to compensate the constant frequency fluctuations in the electrical grid. To do so, hydraulic ... -
Promoting lab engagement in experimental compressible flow modelling
(European Society for Engineering Education (SEFI), 2022)
Conference report
Open AccessThe present work depicts the development of an experimental equipment that reveals compressible fluid dynamics, while collecting data from an incompressible flow like water in an open-channel. It consists of an extensive ... -
Re-utilización de materiales domésticos al final de su vida útil como solución simple, sostenible y de bajo coste para la rehabilitación express de edificios antiguos y vulnerables: análisis térmico y acústico
(Universidad de Cantabria, 2022)
Conference report
Restricted access - publisher's policyEste documento tiene como objetivo investigar la posibilidad de convertir materiales domésticos al final de su vida útil (EoLHM), como ropa o embalajes, en materiales aislantes térmicos y acústicos de bajo costo para la ...
