    • High-fidelity simulations of the mixing and combustion of a technically premixed hydrogen flame 

      Mira Martínez, Daniel; Both, Ambrus; Lehmkuhl Barba, Oriol; Gomez Gonzalez, Samuel; Forck, Jonathan; Tanneberger, Tom; Stathopoulos, Panagiotis; Paschereit, Christian Oliver (MCM, 2021)
      Conference lecture
      Open Access
      Numerical simulations are used here to obtain further understanding on the flashback mechanism of a technically premixed hydrogen flame operated in lean conditions. Recent work from the authors (Mira et al., 2020) showed ...
    • Low-dissipation finite element strategy for low Mach number reacting flows 

      Both, Ambrus; Lehmkuhl Barba, Oriol; Mira Martínez, Daniel; Ortega, Marc (Elsevier, 2020-03-30)
      Article
      Open Access
      The present paper extends the conservative finite element convective scheme proposed by Charnyi et al.(Journal of Computational Physics 337, 2017, 289–308) originally formulated for incompressible flows to the low Mach ...
    • Numerical characterization of a technically premixed hydrogen flame under conditions close to flashback 

      Mira Martínez, Daniel; Lehmkuhl Barba, Oriol; Both, Ambrus; Stathopoulos, Panagiotis; Tanneberger, Tom; Reichel, Thoralf G.; Paschereit, Christian Oliver; Vázquez, Mariano; Houzeaux, Guillaume (Springer, 2020-03)
      Article
      Open Access
      This work presents a numerical study of a technically premixed swirling combustor with central air injection at conditions close to flashback using large-eddy simulation with flamelet modelling. This burner has the ...
    • Optimization of the progress variable definition using a genetic algorithm for the combustion of complex fuels 

      Both, Ambrus; Mira Martínez, Daniel; Lehmkuhl Barba, Oriol (MCM, 2021)
      Conference lecture
      Open Access
      In this work counterflow diffusion flamelets of n-heptane and air are used at stable and unsteady extinguishing conditions for building a thermo-chemical database for Computational Fluid Dynamics (CFD) calculations. The ...
    • Semi implicit solver for high fidelity LES/DNS solutions of reacting flows 

      Surapaneni, Anurag; Mira Martínez, Daniel (MCM, 2021)
      Conference lecture
      Open Access
      A semi-implicit/point-implicit stiff solver (ODEPIM) for integrating chemistry in context of high fidelity LES/DNS simulations is presented. A detailed overview of the algorithm and its numerical formulation is discussed. ...
