Lagrangian Formulation of Turbulent Premixed Combustion [PDF]
Physical Review Letters, 2011 The Lagrangian point of view is adopted to study turbulent premixed combustion. The evolution of the volume fraction of combustion products is established by the Reynolds transport theorem. It emerges that the burned-mass fraction is led by the turbulent particle motion, by the flame front velocity, and by the mean curvature of the flame front.

Turbulent burning velocity in combustion chamber of SI engine fueled with compressed biogas
Vietnam Journal of Mechanics, 2015 Turbulent burning velocity is the most important parameter in analyzing pre-mixed combustion simulation of spark ignition engines. It depends on the laminar burning velocity and turbulence intensity in the combustion chamber.

Flamelet Analysis of Turbulent Combustion [PDF]
, 2005 Three-dimensional direct numerical simulations are performed of turbulent combustion of initially spherical flame kernels. The chemistry is described by a progress variable which is attached to a flamelet library. The influence of flame stretch and curvature on the local mass burning rate is studied and compared to an analytical model. It is found that
