      The main objective of this paper is to present a numerical resolution of a suction muffler configuration by using an in-house object oriented CFD & HT code TermoFluids (Lehmkuhl et al. 2007), able to handle tridimensional ...
    • A dynamic wall model for large eddy simulation on unstructured meshes. Application to wind turbine dedicated airfoils 

      Calafell Sandiumenge, Joan; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María; Oliva Llena, Asensio; Pérez Segarra, Carlos David (Begell House, 2015)
      Conference report
      Restricted access - publisher's policy
      Large eddy simulations (LES) of wall resolved flows at high Reynolds number are still computation-ally demanding. In the present work, a new Dynamic Wall Model (DWM) for LES is presented. The methodology, implemented on ...

      Open Access
      This paper presents an advanced methodology for the detailed modeling of the heat transfer and fluid dynamics phenomena in solar tower receivers. It has been carried out in the framework of a more ambitious enterprise which ...
    • Characteristics of the near wake region behind a cylinder at critical and super-critical Reynolds numbers 

      Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol; Chiva Segura, Jorge; Borrell Pol, Ricard; Oliva Llena, Asensio (Begell House, 2015)
      Conference report
      Restricted access - publisher's policy
      Large-eddy simulations (LES) of the flow past a circular cylinder are used to investigate the characteristics of the near wake region at Reynolds numbers Re = 2.5 × 105 - 8.5 × 105. This range encompasses both the critical ...

      Conference report
      Open Access
      Creating a highly parallelizable code is a challenge and development for distributed memory machines (DMMs) can be very different form developing a serial code in term of algorithms and structure. For this reason, many ...
