Direct Numerical Simulation of premixed ammonia/hydrogen flames: the effects of thermo-diffusive instabilities
Gaucherand, Jessica (Doctoral theses at NTNU;2023:377, Doctoral thesis, 2023)In order to phase out traditional fuel from the energy mix to reduce CO2 emissions and meet the large energy demand, the combustion of carbon-free fuels needs to be considered. This thesis investigates the combustion of ... -
DNS of Turbulent Premixed Ammonia/Hydrogen Flames: The Impact of Thermo-Diffusive Effects
Gaucherand, Jessica; Netzer, Corinna; Laera, Davide; Poinsot, Thierry (Journal article; Peer reviewed, 2023)Direct Numerical Simulations (DNS) of three-dimensional premixed turbulent hydrogen-air flames enriched with 19%, 36%, 44% and 57% of NH (in volume) are performed. Starting from an equivalence ratio of 0.44 for the case ... -
Intrinsic instabilities of hydrogen and hydrogen/ammonia premixed flames: Influence of equivalence ratio, fuel composition and pressure
Gaucherand, Jessica; Laera, Davide; Netzer, Corinna; Poinsot, Thierry (Peer reviewed; Journal article, 2023)Premixed lean hydrogen-air flames exhibit instabilities due to hydrodynamic instabilities but also thermo-diffusive instabilities. However, in the case of ammonia/hydrogen blends, the effect of ammonia addition on instabilities ...
