Impact of fuel chemistry on the global consumption speed of large hydrocarbon fuel/air flames
Aaron J. Fillo, Jonathan Bonebrake, David L. Blunck
Large hydrocarbon fuels are used for ground and air transportation and will be for the foreseeable future. Despite their extensive use, turbulent combustion of large hydrocarbon fu…
Assessing diffusion model impacts on enstrophy and flame structure in turbulent lean premixed flames
Aaron J. Fillo, Peter E. Hamlington, Kyle E. Niemeyer
Diffusive transport of mass occurs at small scales in turbulent premixed flames. As a result, multicomponent mass diffusion, which is often neglected in direct numerical simulation…
Assessing the impact of multicomponent diffusion in direct numerical simulations of premixed, high-Karlovitz, turbulent flames
Aaron J. Fillo, Jason Schlup, Guillaume Blanquart +1
Implementing multicomponent diffusion models in numerical combustion studies is computationally expensive; to reduce cost, numerical simulations commonly use mixture-averaged diffu…
A fast, low-memory, and stable algorithm for implementing multicomponent transport in direct numerical simulations
Aaron J. Fillo, Jason Schlup, Guillaume Beardsell +2
Implementing multicomponent diffusion models in reacting-flow simulations is computationally expensive due to the challenges involved in calculating diffusion coefficients. Instead…
