Kinetic and Fluid Dynamics Modelling of a Methane/Hydrogen Jet Flames in Diluted Coflow
TL;DR: In this paper, the effects of various modeling strategies on the prediction of the JHC flame structure using the CFD code FLUENT 6.3.26 have been discussed and validated in the conditions of interest using recent literature data and support the proposed approach as a useful tool for optimizing the design of new burners also in the MILD combustion regime.

The prediction of laminarization with a two-equation model of turbulence
W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the local turbulent viscosity is determined from the solution of transport equations for the turbulence kinetic energy and the energy dissipation rate, and the predicted hydrodynamic and heat-transfer development of the boundary layers is in close agreement with the measured behaviour.
