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…
Assessment of the Flamelet Generated Manifold method with preferential diffusion modelling for the prediction of partially premixed hydrogen flames
Eduardo Javier Pérez-Sánchez, Emiliano Manuel Fortes, Daniel Mira
This study presents a systematic analysis of the capabilities of a flamelet model based on Flamelet Generated Manifolds (FGM) to reproduce preferential diffusion effects in partial…
Dynamic load balance of chemical source term evaluation in high-fidelity combustion simulations
Guillem Ramírez-Miranda, Daniel Mira, Eduardo J. Pérez-Sánchez +4
This paper presents a load balancing strategy for reaction rate evaluation and chemistry integration in reacting flow simulations. The large disparity in scales during combustion i…
