Sooting turbulent jet flame: characterization and quantitative soot measurements [PDF]
Computational fluid dynamics (CFD) modelers require high-quality experimental data sets for validation of their numerical tools. Preferred features for numerical simulations of a sooting, turbulent test case flame are simplicity (no pilot flame), well-defined boundary conditions, and sufficient soot production.

Simultaneous measurements of flame geometry and flow field by OH-PLIF/Stereo PIV
It is difficult to understand turbulent combustion, because the combustion process is very complex and unsteady. One of the useful parameters for discussion of the unsteady flame behaviors is the flame stretch rate, which is evaluated by local flame ...

Anchoring of premixed jet flames in vitiated crossflow with pulsed nanosecond spark discharge
This paper deals with the effect of non-equilibrium plasma on the anchoring of a premixed jet flame in hot vitiated crossflow at atmospheric pressure. The turbulent vitiated crossflow was generated by an array of 4×4 premixed turbulent jet flames burning

Measurement of turbulent flame speed of natural gas/air mixtures at elevated pressure [PDF]
Turbulent flame speeds were measured over a range of pressures to 0.8 MPa using a jet flow apparatus fired with a synthetic mixture representing a mid-European natural gas. The equivalence ratio empty set was 0.9.

Reynolds number dependence of scalar fluctuations in a high Schmidt number turbulent jet [PDF]
The scalar rms fluctuations in a turbulent jet were investigated experimentally, using high-resolution, laser-induced fluorescence techniques. The experiments were conducted in a high Schmidt number fluid (water), on the jet centerline, over a jet ...
