Enhancement of turbulent flame speed of V-shaped flames in fractal-grid-generated turbulence
Combustion and Flame, 2016 A variety of fractal grids is used to investigate how fractal-grid-generated turbulence affects the turbulent flame speed for premixed flames. The grids are placed inside a rectangular duct and a V-shaped flame is stabilized downstream of the duct, using a metal wire. This flame is characterized using OH-LIF.

Simulation of Hydrogen-Air-Diluents Mixture Combustion in an Acceleration Tube with FlameFoam Solver
Energies, 2021 During a severe accident in a nuclear power plant, hydrogen can be generated, leading to risks of possible deflagration and containment integrity failure. To manage severe accidents, great experimental, analytical, and benchmarking efforts are being made

Self-Turbulent Flame Speeds [PDF]
Flow, Turbulence and Combustion, 2011 This paper reports an experimental investigation of premixed propane andmethane-air flames propagating freely in tubes 1.5 m long and with diameters rangingfrom 26 to 141 mm. The thermo-acoustic instability was eliminated by means of anovel acoustic absorber placed at the closed end of the tube.

Variation of Flame Displacement Speed in a Turbulent Premixed Flame [PDF]
Australasian Fluid Mechanics Conference (AFMC), 2020 Modelling of the flame displacement speed is of interest in many Large Eddy Simulation (LES) frameworks including the Flame Surface Density approach. In this study, a Direct Numerical Simulation (DNS) dataset is used to calculate the displacement speed in a premixed, methane–air, round jet flame in the thin reaction zone (TRZ) regime.
