    In this work an hydrogen enriched methane flame in a non-premixed configuration is studied, which corresponds to the DLR flame A. Large Eddy Simulation (LES) will be used to numerically analyse the case. Unstructured meshes ...
  • Modelization of the Low-Mach Navier Stokes equations in unstructured meshes 

    Chiva Segura, Jorge; Ventosa, Jordi; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David (2011)
    Conference lecture

    In this paper a Low-Mach number approximation of the Navier Stokes Equations in unstructured meshes is presented. Both staggered and collocated formulations for unstructured grids will be used.The aim is to develop a ...
  • Non-Oberbeck-Boussinesq natural convection in a tall differentially heated cavity 

    Kizildag, Deniz; Ventosa, Jordi; Rodríguez Pérez, Ivette María; Oliva Llena, Asensio (2010)
    Conference report
    Open Access
    Turbulent flow in a water-filled rectangular parallelepiped tank of an integrated solar collector is analyzed by means of a set of two and three dimensional simulations. The geometry and the working conditions of the ...
  • Numerical simulation of the turbulent fluid flow through valves based on low mach models 

    Rigola Serrano, Joaquim; Lehmkuhl Barba, Oriol; Ventosa, Jordi; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2012)
    Conference report
    Restricted access - publisher's policy
    The aim of the present paper is to carry out a group of numerical experiments over the fluid flow through the valve reed, using the CFD&HT code TermoFluids, an unstructure d and parallel object-oriented CFD code for accurate ...
  • Study of the autoignition of a hydrogen jet in a turbulent co-flow of heated air using LES modelling 

    Muela Castro, Jordi; Ventosa, Jordi; Lehmkuhl Barba, Oriol; Oliva Llena, Asensio (2013)
    Conference report
