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…

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…
