    • A CFD framework for offshore and onshore wind farm simulation 

      Avila, Matias; Gargallo-Peiró, Abel; Folch, Arnau (IOP Publishing, 2017)
      Article
      Open Access
      We present a wind simulation framework for offshore and onshore wind farms. The simulation framework involves an automatic hybrid high-quality mesh generation process, a pre-processing to impose initial and boundary ...
    • A wind field downscaling strategy based on domain segmentation and transfer functions 

      Barcons, Jordi; Avila, Matias; Folch, Arnau (Wiley, 2018-02-06)
      Article
      Open Access
      This paper presents a novel methodology for mesoscale‐to‐microscale downscaling of near‐surface wind fields. The model chain consists on the Weather Research and Forecast mesoscale model and the Alya‐CFDWind microscale ...
    • Diurnal cycle RANS simulations applied to wind resource assessment 

      Barcons, Jordi; Avila, Matias; Folch, Arnau (Wiley, 2019-02)
      Article
      Open Access
      Microscale computational fluid dynamics (CFD) models can be used for wind resource assessment on complex terrains. These models generally assume neutral atmospheric stratification, an assumption that can lead to inaccurate ...
    • Mesh generation, sizing and convergence for onshore and offshore wind farm Atmospheric Boundary Layer flow simulation with actuator discs 

      Gargallo Peiró, Abel; Avila, Matias; Owen, Herbert; Prieto-Godino, Luis; Folch, Arnau (Elsevier, 2018-12)
      Article
      Open Access
      A new mesh generation process for wind farm modeling is presented together with a mesh convergence and sizing analysis for wind farm flow simulations. The generated meshes are tailored to simulate Atmospheric Boundary Layer ...
    • The ALEX17 diurnal cycles in complex terrain benchmark 

      Sanz Rodrigo, Javier; Santos, Pedro; Chávez Arroyo, R; Avila, Matias; Cavar, Dalibor; Lehmkuhl Barba, Oriol; Owen, Herbert; Li, R; Tromeur, Eric (IOP Publishing, 2021)
      Article
      Open Access
      The NEWA ALEX17 experiment was conducted with the objective of characterizing the wind conditions upstream of the Alaiz Test Site for the validation of flow models. From the intensive operational period, a case study has ...
    • Wall‐modeled large‐eddy simulation in a finite element framework 

      Owen, Herbert; Chrysokentis, Georgios; Avila, Matias; Mira, Daniel; Houzeaux, Guillaume; Cajas, Juan Carlos; Lehmkuhl Barba, Oriol (Wiley, 2020-01)
      Article
      Open Access
      This work studies the implementation of wall modeling for large‐eddy simulation in a finite element context. It provides a detailed description of how the approach used by the finite volume and finite differences communities ...
