  • Numerical modal analysis of a Kaplan turbine runner 

    Roig Bauzà, Rafel; Torre Rodríguez, Óscar de la; Jou Santacreu, Esteban; Escaler Puigoriol, Francesc Xavier (2020)
    Conference lecture
    Open Access
    The aim of the research has been to investigate the change of dynamic behavior of a Kaplan turbine runner when submerged in still water. More specifically, the effects of the added mass on the modes of vibration have been ...
  • Near-interface modeling in large-eddy simulation of two-phase turbulent flow 

    Jofre Cruanyes, Lluís; Dodd, Michael S. (2020)
    Conference report
    Open Access
    The smallest hydrodynamic length scales in interfacial turbulent flow are located at the interface between phases/fluids as a result of two-way coupling phenomena. These interface-generated scales are, typically, several ...
  • Gears or rotors-three approaches to design of working units of hydraulic machines 

    Stryczek, Jaroslaw; Bednarczyk, S.; Codina Macià, Esteban; Gámez Montero, Pedro Javier; Ivanovic, Lozica; Matejic, Milos (Institute of Physics (IOP), 2019)
    Conference report
    Open Access
    The gerotor pump has many advantages over other hydraulic pumps, such as high reliability, compactness, lower noise in running conditions etc. Considering the increasingly stringent regulations in the field of environmental ...
  • Soleil-X: turbulence, particles, and radiation in the Regent programming language 

    Torres, Hilario; Papadakis, Manolis; Jofre Cruanyes, Lluís (2019)
    Conference report
    Open Access
    The Predictive Science Academic Alliance Program (PSAAP) II at Stanford University is developing an exascale-ready multi-physics solver to investigate particle-laden turbulent flows in a radiation environment for solar ...
  • Uncertainty quantification in large eddy simulations of a rich-dome aviation gas turbine 

    Jofre Cruanyes, Lluís (2017)
    Conference report
    Restricted access - publisher's policy
    In this work, a rich-dome aviation combustor operating over a range of high-power conditions is investigated using multiple Large Eddy Simulations (LES). The LES flow solutions are obtained with CharLES, a massively-parallel ...
  • Interface dynamics in the transcritical flow of liquid fuels into high-pressure combustors 

    Jofre Cruanyes, Lluís (2017)
    Conference report

  • Design and development of a kinetic energy harvester device for oceanic drifter applications 

    Carandell Widmer, Matias; Toma, Daniel; Carbonell Ventura, Montserrat; Gasulla Forner, Manuel; Río Fernandez, Joaquín del (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    A novel electronic energy harvester (EH) has been developed for oceanic undrogued drifter applications. First, spherical body motion simulation has been performed at sea environment in Orcaflex. Results help to understand ...
  • Wind tunnel testing of a high aspect ratio wing model 

    Cooper, Jonathan E.; Cook, Robbie G; Francois, G.; Torre Rodríguez, Óscar de la; Neild, Simon A.; Lowenberg, Mark H.; Alexander, S. S.; Coetzee, E. B.; Evans, M. (Curran, 2019)
    Conference report
    Open Access
    There is much current interest in the development of High Aspect Ratio Wing (HARW) designs for improved aircraft performance. However, there are a lack of relevant data sets available to validate aeroelastic modelling ...
  • Active flow control on SD7003 airfoil using synthetic jets 

    Tousi, Navid Monshi; Bergadà Granyó, Josep Maria; Rodríguez Pérez, Ivette María (2019)
    Conference report
    Restricted access - publisher's policy
    The present paper focuses on applying the Active Flow Control (AFC) technology on the Selig-Donovan 7003 (SD7003) airfoil at Reynolds number 60,000, the idea is to employ synthetic jets in order to modify the lift and drag ...
  • CFD study of the effects of ingested bodies on the RSI of hydraulic turbines 

    Guardo Zabaleta, Alfredo de Jesús; Fontanals García, Alfred; Valero Ferrando, Ma. del Carmen; Egusquiza Estévez, Eduard (2018)
    Conference report
    Open Access
    The ingestion of large bodies in hydraulic turbines can produce blockage in the runner and/or the distributor, modifying the amplitude and uniformity of pressure pulsations and generating large ...
  • Design of a global maximum power point tracking (GMPPT) for PV array based on precise PV shadow modem 

    García-Gutiérrez, Luis; Bressan, Michael; Jiménez, Fernando; Heras Jiménez, Salvador Augusto de las; Alonso, Corinne (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
    Open Access
    This paper presents the modeling of a photovoltaic system under complex shading conditions. The approach integrates a complete PV array with each cell modeled separately including shadow coefficients depending on a ...
