International Journal of Hydrogen Energy, 2013 A critical review and rethinking of hydrogen jet flame research is carried out. Froude number only based correlations are shown to be deficient for under-expanded jet fires. The novel dimensionless flame length correlation is developed accounting for effects of Froude, Reynolds, and Mach numbers. The correlation is validated for pressures 0.1–90.0 MPa,

LIFTED LAMINAR JET DIFFUSION FLAMES [PDF]
Combustion Science and Technology, 2005 This paper addresses the numerical description of lifted flames in axisymmetric laminar coflow jets. The analysis considers moderately large values of the Reynolds number, when the boundary-layer approximation can be used to describe the slender mixing region that extends between the jet exit and the flame, providing the profiles of velocity and ...

Simultaneous measurements of flame geometry and flow field by OH-PLIF/Stereo PIV
Nihon Kikai Gakkai ronbunshu, 2016 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 ...

Experimental Study on Bluff-Body Stabilized Premixed Flame with a Central Air/Fuel Jet
Energies, 2017 Bluff-body flame holders are commonly employed in many industrial applications. A bluff-body is usually adopted to enhance the downstream mixing of the combustion products and the fresh fuel-air mixtures, thus to improve the flame stability and to ...

Numerical Simulation of Hot Jet Detonation with Different Ignition Positions
Applied Sciences, 2019 Ignition position is an important factor affecting flame propagation and deflagration-to-detonation transition (DDT). In this study, 2D reactive Navier−Stokes numerical studies have been performed to investigate the effects of ignition position on ...
