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.

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.

Three-Dimensional Direct Numerical Simulation of Near-Field Ozone-Enhanced Lean Premixed Syngas Turbulent Jet Flame

Energies, 2022
Due to its enhancement in the flame speed, ozone added in lean premixed syngas turbulent jet flame was investigated by the three-dimensional direct numerical simulation method in the near field of the flame.

Study of laminar flame speed measurement under high pressure condition using double kernel method by laser-induced breakdown ignition

Journal of Thermal Science and Technology, 2020
In order to understand turbulent combustion and its combustion characteristics, laminar flame speed is often used. Laminar flame speed plays an important role in turbulent combustion models used in engine combustion simulation.
