    • Comparative study of subfilter scalar dissipation rate and mixture fraction variance models 

      Ventosa Molina, Jordi; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David; Muela Castro, Jordi; Oliva Llena, Asensio (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Accurate characterisation of mixing at the subfilter level is a critical aspect in many LES combustion models, such as flamelet based and Conditional Moment Closure models. Several models can be found in the literature, ...

    • Distributed tabulation of flamelet lookup tables 

      Abel, Nicholas; Borrell Pol, Ricard; Mira Martínez, Daniel (Barcelona Supercomputing Center, 2022-05)
      Text en actes de congrés
      Accés obert
      One of the fundamental questions in combustion simulation is how to account for detailed chemistry effects, while controlling both the error of the chemical scheme and the computational cost. Combustion chemistry is ...

    • Modelling thermoacoustic instabilities with a graphical interface (Simulink) 

      Dilmé Punset, Jordi (Universitat Politècnica de Catalunya / Imperial College London, 2010)
      Projecte/Treball Final de Carrera
      Accés obert
      Combustion units frequently experience thermoacoustic instabilities, also known as combustion oscillations, which are consequence of the internal coupling between acoustic waves and unsteady heat release. Deterioration ...

    • Study for the numerical resolution of combustion phenomena in burners 

      Godayol Capdevila, Èric (Universitat Politècnica de Catalunya, 2016-06-17)
      Projecte Final de Màster Oficial
      Accés obert
      Combustion is a complex phenomenon of interest that combines chemical reactions and turbulent flows. Resolution of both problems is a difficult task. On the one hand, chemical reactions introduce a large amount of species ...
