    • On the development and application of intrusive sensors for two-phase flows characterization in complez environments 

      Monrós Andreu, Guillem; Prades, O.; Martínez Cuenca, Raúl; Torró Cueco, Salvador Francisco; Chiva Vicent, Sergio (SARTI, 2023)
      Article
      Accés obert
      Intrusive sensors are widely employed in numerous industrial applications to determine the phase fraction in gas-liquid two-phase flows. Such applications include those in the chemical, nuclear, and oil industries. This ...

    • Opposed bubbly jets at different impact angles: jet structure and bubble properties 

      Suñol Galofre, Francesc Xavier; González Cinca, Ricardo (2010-08)
      Article
      Accés restringit per política de l'editorial
      The structure of two colliding water jets containing small gas bubbles is studied experimentally. The effects of the separation distance between jets, as well as the orientation angle, on the spatial distribution of ...

    • Optimization-based level-set re-initialization: a robust interface preserving approach in multiphase problems 

      Hashemi, Alireza; Hashemi, Mohammad Reza; Ryzhakov, Pavel; Rossi, Riccardo (Elsevier, 2024-02)
      Article
      Accés obert
      In spite of its overall efficiency and robustness for capturing the interface in multiphase fluid dynamics simulations, the well-known shortcoming of the level-set method is associated with the lack of a systematic approach ...

    • Parallel Unstructured Conservative Level-Set (UCLS) method for two-phase flow with Marangoni effect 

      Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Parallel Computational Fluid Dynamics (ParCFD), 2023)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work presents a massively parallelized Unstructured Conservative Level-Set (UCLS) method for two-phase flow with variable surface tension, i.e., Marangoni effect. This method employs a multiple-marker UCLS approach ...

    • Simulation numérique du dispositif microfluidique bille d'un stylo 

      Badreddine, Bourtal (Universitat Politècnica de Catalunya, 2008-06)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      La simulation numérique tend à prendre de plus en plus d’importance dans le développement des projets scientifiques actuels. Les simulations numériques ont l’avantage, par rapport aux expérimentations, d’être moins ...

    • Thermal Systems Oriented Two-Phase Heat Exchanger Models. Focus on Numerical Robustness 

      Ablanque Mejía, Nicolás; Torras Ortiz, Santiago; Oliet Casasayas, Carles; Rigola Serrano, Joaquim (Purdue University, 2022)
      Comunicació de congrés
      Accés obert
      The simulation of complex refrigeration architectures (that usually include vapor compression cycles) provides useful information for design, study and optimization purposes. Such arrangements may include several interconnected ...

    • Three dimensional modeling of liquid droplet spreading on solid surface: an enriched finite element/level-set approach 

      Hashemi, Mohammad Reza; Ryzhakov, Pavel; Rossi, Riccardo (2021-10)
      Article
      Accés obert
      A physically consistent approach is introduced to simulate dynamics of droplets in contact with solid substrates. The numerical method is developed by introducing the molecular–kinetic model within the framework of the ...

    • Two-phase turbulent kinetic energy budget computation in co-current Taylor bubble flow 

      Frederix, E.M.A.; Tajfirooz, S; Hopman, Johannes Arend; Fang, Jun; Merzari, Elia; Komen, E.M.J. (Taylor & Francis Group, 2023-02-13)
      Article
      Accés obert
      Simulation of two-phase flows is relevant for reactor design and safety at normal operation or during accident scenarios. Often, the two-phase flow is in a regime in which slugs are formed or where the flow stratifies. ...

    • Unstructured Conservative Level-Set (UCLS) method for mass transfer in bubble swarms with high physical properties ratios 

      Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Begell House, 2024)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work introduces a parallel Unstructured Conservative Level-Set (UCLS) method for reactive mass transfer in two-phase flows with a high-density ratio. The proposed method employs the multiple-marker approach to circumvent ...

    • Unstructured Level-Set Method For Saturated Liquid-Vapor Phase Change 

      Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
      Text en actes de congrés
      Accés obert
      A novel conservative level-set method for saturated liquid-vapor phase change on unstruc-tured meshes is introduced. Transport equations are discretized by the finite-volume method on col-located unstructured grids. Mass ...
