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 p…
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…
Vortex Stretching of Non-premixed, Diluted Hydrogen/Oxygen Flamelets
Wes Hellwig, Xian Shi, William A. Sirignano
A three-dimensional flamelet model considering vortex stretching with unitary Lewis number is used to simulate diluted hydrogen-oxygen diffusion flames. Non-reacting nitrogen is us…
Unsteady Three-dimensional Rotational Flamelet
William A. Sirignano
A new unsteady flamelet model is developed to be used for sub-grid modeling and coupling with the resolved flow description for turbulent combustion. Difficulties with prior unstea…
