Effect of Temperature Conditions on Flame Evolutions of Turbulent Jet Ignition
Turbulent jet ignition technology can significantly improve lean combustion stability and suppress engine knocking. However, the narrow jet channel between the pre-chamber and the main chamber leads to some difficulties in heat exchange, which ...

Propagation Properties of Turbulent Premixed Flames Neutral for Thermo-Diffusive Effects
Burning velocity is one of the important properties of premixed turbulent flames. Premixed turbulent flames are, in general, subjected to the thermo-diffusive effects in addition to the increase in the flame front area due to the influence of turbulence.

Flame trajectory of a non-vertical turbulent buoyant jet flame
This paper presents a theoretical and experimental study on the flame trajectory of a non-vertical turbulent diffusion flame in still air. A series of propane turbulent flame tests (inner diameter of the burner: d=13 mm) with different initial Froude ...

A Lagrangian-based flame index for the transported probability density function method
We propose a new flame index for the transported probability density function (PDF) method. The flame index uses mixing flux projections of Lagrangian particles on mixture fraction and progress variable directions as the metrics to identify the ...
