Preferential and differential diffusion in RANS simulation of lean hydrogen flames with tabulated chemistry
Alex M. Garcia, Emiliano M. Fortes, Eduardo J. Pérez-Sánchez +6
Lean hydrogen flames are prone to thermo-diffusive instabilities due to preferential and differential diffusion effects, posing significant challenges for their modeling in computa…
Large-eddy simulations of a lean hydrogen premixed turbulent jet flame with tabulated chemistry
Emiliano M. Fortes, Eduardo J. Pérez-Sánchez, Temistocle Grenga +3
Large-eddy simulations (LES) of a planar turbulent lean hydrogen-air jet flame at Re = 11000 are performed using a tabulated flamelet model based on mixture-averaged diffusion that…
Analysis of thermodiffusive instabilities in hydrogen premixed flames using a tabulated flamelet model
Emiliano Manuel Fortes Soplanes, Eduardo Javier Pérez Sánchez, Ambrus Both +2
Preferential diffusion plays a critical role in the evolution of lean premixed hydrogen flames, influencing flame surface corrugation and overall flame behavior. Simulating such fl…
