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…
On the spatial structure and intermittency of soot in a lab-scale gas turbine combustor: Insights from large-eddy simulations
Leonardo Pachano, Daniel Mira, Abhijit Kalbhor +1
This work presents a numerical investigation of soot formation in the Cambridge lab-scale gas turbine combustor. Large-eddy simulations (LES) of a swirl-stabilized ethylene flame a…
Projection-based stabilization for high-order incompressible flow solvers
Antonio Blanco-Casares, Vishal Kumar, Daniel Mira +1
This work presents a novel stabilization strategy for the Galerkin formulation of the incompressible Navier-Stokes equations, developed to achieve high accuracy while ensuring conv…
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…
