Experimental Investigation of Air–Fuel Mixing Effects on Flame Characteristics in a Direct fired Burner

Energies, 2021
The length and pattern of air–fuel mixing plays a significant role in the uniformity, flame temperature, and emission characteristics, which can lead to a superior product quality in a non-oxidizing direct fired burner for a cold-rolled steel plate ...

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 ...
