  • Minimization procedure of experimental tests for calibration purposes, within HVAC&R energy efficiency framework 

    Morales Ruíz, Sergio; Oliet Casasayas, Carles; Castro González, Jesús; Rigola Serrano, Joaquim; Oliva Llena, Asensio (2019)
    Conference report
    Open Access
    Simulation models and predictive tools need to be fast, accurate and robust at the same time. The models that have to provide numerical solutions under transient conditions for a long period of time need to be simple with ...

  • An efficient Two-Layer wall model for accurate numerical simulations of aeronautical applications 

    Calafell Sandiumenge, Joan; Trias Miquel, Francesc Xavier; Oliva Llena, Asensio (2019)
    Conference report
    Open Access
    Two-Layer wall models have been widely studied since they allow wall modeled Large Eddy Simulationsof general non-equilibrium flows. However, they are plagued by two persistent problems, the "log-layermismatch" and the ...

    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 ...

  • Assessment and comparison of a recent kinematic sensitive subgrid length scale in Hybrid RANS-LES 

    Pont Vilchez, Arnau; Trias Miquel, Francesc Xavier; Revell, Alistair; Oliva Llena, Asensio (Springer Nature, 2020)
    Conference report
    Restricted access - publisher's policy
    A recent kinematic sensitive subgrid length scale, Δlsq, initially developed for LES applications, is now considered for DES. Even though it is presented as a subgrid length scale, instead of a grey area mitigation (GAM) ...

    Ablanque Mejía, Nicolás; Oliet Casasayas, Carles; Rigola Serrano, Joaquim; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David (Purdue University, 2014)
    Conference report
    Restricted access - publisher's policy
    This work presents a flexible numerical platform to simulate a whole household refrigeration unit taking into account both the refrigeration cycle itself and the refrigerated compartments network. The methodology implemented ...

  • Numerical Model of Capillary Tubes: Enhanced Performance and Study of Non-Adiabatic Effects 

    Ablanque Mejía, Nicolás; Oliet Casasayas, Carles; Rigola Serrano, Joaquim; Pérez Segarra, Carlos David (Purdue University, 2014)
    Conference report
    Restricted access - publisher's policy
    In the present work a numerical model to simulate the thermal and fluid-dynamic phenomena inside non-adiabatic capillary tubes is presented. It consists of an improved version of the distributed model detailed in Ablanque ...

  • Mapping Venturi cavitation in a new closed loop facility devoted to study thermodynamic effects
