    Conference report
    Open Access
    The integration of encapsulated PCM in a structured thermal energy storage system is studied. The fluid and filler material are discretized using a one-dimensional approach, while the PCM is discretized two-dimensionally. ...

    Emission reduction and decarbonisation in the industry are crucial for low-carbon industry and energy transition at the global level. Replacing traditional fossil fuel with clean energy is an effective approach to reduce ...
  • On the validation of numerical simulation with experimental results on compressible turbulent flow in an inertial particle separator device 

    Bahramian, Linda; Amani, Ahmad; Rigola Serrano, Joaquim; Oliet Casasayas, Carles; Pérez Segarra, Carlos David (Institute of Physics (IOP), 2024)
    Conference report
    Open Access
    To remove particles from entering the engine or Environmental Control System (ECS), an Inertial Particle Separator (IPS) can be situated in the intake. In IPS, a rapid change in flow direction is induced, and particles ...
  • Experimental and numerical pressure drop investigation of a protruding tube microchannel heat exchanger 

    Settati, Mohamed; Oliet Casasayas, Carles; Sanmartí Perona, Oriol; Oliva Llena, Asensio (Institute of Physics (IOP), 2024)

    Santos Serrano, Daniel; Rigola Serrano, Joaquim; Castro González, Jesús; Trias Miquel, Francesc Xavier (Institute of Physics (IOP), 2024)
    Conference report
    Open Access
    In this work, a general collocated and unconditionally stable framework on unstructured meshes for solving Conjugate Heat Transfer (CHT) problems is presented by means of preserving the underlying symmetries of the continuous ...
  • Parametric study of structured thermocline storage systems 

    Vera i Fernández, Jordi; Sanmartí Perona, Oriol; Torras Ortiz, Santiago; Pérez Segarra, Carlos David (2022)
    Conference report
    Restricted access - publisher's policy
    A thermal accumulator system for concentrated solar power is modeled to perform a parametric study. The thermal accumulation system is a type of structured thermocline where there is a solid filler material with some ...
  • Optimized approach for CFD simulations of HVAC systems with grill air diffusers 

    Vera i Fernández, Jordi; Schillaci, Eugenio; Rigola Serrano, Joaquim; Oliet Casasayas, Carles (International Institute of Refrigeration, 2023)
    Conference report
    Restricted access - publisher's policy
    A proper CFD simulation of air distribution within a room requires the correct representation of inlet conditions from ventilation grids. Those elements are usually characterized by blades with a certain inclination angle ...
  • DNS and RANS simulations of a coil heat exchanger immersed in a tank 

    Vera i Fernández, Jordi; Torras Ortiz, Santiago; Schillaci, Eugenio; Oliva Llena, Asensio (Begell House, 2023)
    Conference lecture
    Restricted access - publisher's policy
    The operation of heat exchangers in a thermal system can be described by simple heat transfer equations. The heat exchange is normally defined by a global heat transfer coefficient, which takes into account internal and ...
  • Assessment of LES models for a fully developed windturbine array boundary layer 

    Folch Flórez, David; Trias Miquel, Francesc Xavier; Oliva Llena, Asensio (Begell House, 2023)
    Conference report
    Restricted access - confidentiality agreement
    Direct numerical simulations of the incompressible Navier-Stokes equations at high Reynolds numbers are not yet feasible, so dynamically less complex mathematical formulations such as Large Eddy Simulation (LES) have been ...
  • Strategies for increasing the arithmetic intensity on ensemble averaged parallel-in-time simulations 

    Plana Riu, Josep; Trias Miquel, Francesc Xavier; Alsalti Baldellou, Àdel; Oliva Llena, Asensio (Parallel Computational Fluid Dynamics (ParCFD), 2023)
    Conference report
    Restricted access - confidentiality agreement
    Extracting flow statistics from flow simulations requires generally long in- tegration intervals in which a good deal of the time is spent time-averaging the results. In order to avoid this, ensemble averaging can be applied ...
