    Earthquake aftershocks display spatiotemporal correlations arising from their self-organized critical behavior. Dynamic deterministic modeling of aftershock series is challenging to carry out due to both the physical ...
  • Active flow control for external aerodynamics: from micro air vehicles to a full aircraft in stall 

    Lehmkuhl, Oriol; Lozano-Durán, Adrian; Rodríguez Pérez, Ivette María (Institute of Physics (IOP), 2020-04-01)
    Article
    Open Access
    We investigate the aerodynamic performance of active flow control of airfoils and wings using synthetic jets with zero net-mass flow. The study is conducted via wall-resolved and wall-modeled large-eddy simulation using ...
  • Probing the strongly driven spin-boson model in a superconducting quantum circuit 

    Magazzù, Luca; Forn Diaz, Pol; Belyansky, Ron; Orgiazzi, Jean-Luc; Yurtalan, Muhammet; Otto, Martin R.; Lupascu, Adrian; Wilson, Christopher; Grifoni, Milena (2018-04-11)
    Article
    Open Access
    Quantum two-level systems interacting with the surroundings are ubiquitous in nature. The interaction suppresses quantum coherence and forces the system towards a steady state. Such dissipative processes are captured by ...

    Article
    Open Access
    Many software mechanisms for geophysics exploration in oil and gas industries are based on wave propagation simulation. To perform such simulations, state-of-the-art high-performance computing architectures are employed, ...
  • Effects of the actuation on the boundary layer of an airfoil at Reynolds Number Re = 60000 

    Rodríguez Pérez, Ivette María; Lehmkuhl, Oriol; Borrell Pol, Ricard (Springer-Verlag, 2020-05-29)
    Article
    Restricted access - publisher's policy
    Synthetic (zero net mass flux) jets are an active flow control technique to manipulate the flow field in wall-bounded and free-shear flows. The present paper focuses on the role of the periodic actuation mechanisms on the ...
  • Effects of turbulence-chemistry interactions on auto-ignition and flame structure for n-dodecane spray combustion 

    Zhang, Yan; Wang, Hu; Both, Ambrus; Ma, Likun; Yao, Mingfa (2019-06-01)
    Article
    Open Access
    The Engine Combustion Network (ECN) spray A under diesel engine conditions is investigated with a non-adiabatic 5D Flamelet Generated Manifolds (FGM) model with the consideration of detailed chemical kinetic mechanisms. ...
  • Alternating direction implicit time integrations for finite difference acoustic wave propagation: parallelization and convergence 

    Otero Calviño, Beatriz; Rojas, Otilio; Moya, Ferrán; Castillo, José (Elsevier, 2020-06-15)
    Article
    Restricted access - publisher's policy
    This work studies the parallelization and empirical convergence of two finite difference acoustic wave propagation methods on 2-D rectangular grids, that use the same alternating direction implicit (ADI) time integration. ...
  • 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
    Restricted access - publisher's policy
    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 ...
  • HPC compact quasi-Newton algorithm for interface problems 

    Santiago, Alfonso; Zavala Aké, Miguel; Borrell Pol, Ricard; Houzeaux, Guillaume; Vázquez, Mariano (Elsevier, 2020)
    Article
    Restricted access - publisher's policy
    In this work we present a robust interface coupling algorithm called Compact Interface quasi-Newton (CIQN). It is designed for computationally intensive applications using an MPI multi-code partitioned scheme. The algorithm ...
  • Active control of Alfvén eigenmodes inmagnetically confined toroidal plasmas 

    Garcia Muñoz, Manuel; Shaparov, Sergei; Zeeland, Michael A, Van; Ascasibar, Enrique; Cappa, Álvaro; Chen, L; Ferreira, J; Galdon Quiroga, Joaquin; Geiger, Benedikt; González Martin, J; Heidbrink, William W.; Johnson, T; Lauber, Phillipp; Mantsinen, Mervi; Melkinov, Alexander; Nabais, F; Rivero Rodríguez, Juan Francisco; Sanchis Sanchez, Lucía; Schneider, P; Stober, Jörg; Suttrop, Wolfgang; Todo, Yasushi; Vallejos, Pablo; Zonca, Fulvio; AUG and MST1 Teams (IOP Publishing, 2019-03)
    Article
    Open Access
    Alfvén waves are electromagnetic perturbations inherent to magnetized plasmas that can be driven unstable by a free energy associated with gradients in the energetic particles' distribution function. The energetic particles ...
  • Shear Alfvén wave continuum spectrum with bifurcated helical core equilibria 

    Rakha, Allah; Lauber, Philipp; Mantsinen, Mervi Johanna; Spong, Donald (2019-09-09)
    Article
    Restricted access - publisher's policy
    The radial structure of the continuum spectrum of shear Alfvén and Alfvén-acoustic waves in the beta-induced Alfvén eigenmode (BAE) frequency range is modeled for tokamak plasmas in the presence of 3D effects obtained from ...
