Borrell Pol, Ricard; Chiva Segura, Jorge; Lehmkuhl Barba, Oriol; Oyarzun Altamirano, Guillermo; Rodríguez Pérez, Ivette María; Oliva Llena, Asensio (2016)
Article
Accés obertThis paper presents some recent efforts carried out on the expansion of the scalability of TermoFluids multi-physics Computational Fluid Dynamics (CFD) code, aiming to achieve petascale capacity for a single simulation. ... -
Parallel adaptive mesh refinement for large-eddy simulations of turbulent flows
Antepara Zambrano, Óscar; Lehmkuhl Barba, Oriol; Borrell Pol, Ricard; Chiva Segura, Jorge; Oliva Llena, Asensio (Elsevier, 2015-03-30)
Article
Accés obertIn this paper a parallel adaptive mesh refinement (AMR) strategy for large eddy simulations (LES) of turbulent flows is presented. The underlying discretization of the Navier-Stokes equations is based on a finite-volume ... -
The effects of roughness on the boundary layer development of a circular cylinder
Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol; Piomelli, Ugo; Chiva Segura, Jorge; Borrell, Ricard; Oliva Llena, Asensio (European Research Community on Flow, Turbulence, and Conbustion (ERCOFTAC), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper focuses on the effects of surface roughness in the flow past a circular cylinder at different Reynolds numbers. Large eddy simulations of the flow, from subcritical to transcritical Reynolds numbers and at ... -
Turbulent natural convection in an open cavity: a numerical study
Chiva Segura, Jorge; Soria Guerrero, Manel; Oliva Llena, Asensio; Lehmkuhl Barba, Oriol (2009)
Comunicació de congrés
Accés restringit per política de l'editorialIn this paper three-dimensional turbulent natural convection heat transfer in a simplified solar receiver open cavity is studied. Smagorinsky-LES (Large Eddy Simulation) model is chosen for turbulence flow computation. The ... -
Unsteady forces on a circular cylinder at critical Reynolds numbers
Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María; Borrell, Ricard; Chiva Segura, Jorge; Oliva Llena, Asensio (2014-12-23)
Article
Accés obertIt is well known that the flow past a circular cylinder at critical Reynolds number combines flow separation, turbulence transition, reattachment of the flow, and further turbulent separation of the boundary layer. The ...
