Investigation of flame stretch in turbulent lifted jet flame [PDF]
Combustion Science and Technology, 2014 DNS data of a laboratory-scale turbulent lifted hydrogen jet flame has been analysed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations.

Flame trajectory of a non-vertical turbulent buoyant jet flame
Applications in Energy and Combustion Science, 2021 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 ...

Effect of Temperature Conditions on Flame Evolutions of Turbulent Jet Ignition
Energies, 2021 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 ...

A Lagrangian-based flame index for the transported probability density function method
Theoretical and Applied Mechanics Letters, 2022 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 ...
