Strain-Rate-Consistent -Based Non-Premixed Flamelet Model
Sylvain L. Walsh, Yalu Zhu, Feng Liu +1
This numerical study examines a strain-rate inconsistency in the conventional flamelet/progress-variable (FPV) formulation for non-premixed combustion and proposes an alternative c…
Flamelet Model with Epsilon Tracking in a Turbine Stator
Sylvain L. Walsh, Yalu Zhu, Feng Liu +1
Combustion within a two-dimensional turbine stator passage is numerically investigated in the context of the turbine-burner concept using a Reynolds-Averaged Navier-Stokes framewor…
Performance of Flamelet Models with Epsilon Tracking for Diffusion Flame Simulations
Sylvain L. Walsh, Yalu Zhu, Feng Liu +1
This work examines the physical consistency of the conventional Flamelet Progress Variable (FPV) model for diffusion flame simulations and and introduces a new compressible flamele…
Flamelet Connection to Turbulence Kinetic Energy Dissipation Rate
William A. Sirignano, Wes Hellwig, Sylvain L. Walsh
The turbulence kinetic energy dissipation rate , from a turbulent combustion computation using either Reynolds-averaged Navier-Stokes (RANS) or large-eddy simulation (LES), is…
Turbulent Accelerating Combusting Flows with a Methane-Vitiated Air Flamelet Model
Sylvain L. Walsh, Lei Zhan, Carsten Mehring +2
This work presents a numerical study of a diffusion flame in a reacting, two-dimensional, turbulent, viscous, multi-component, compressible mixing layer subject to a large favorabl…
