Flame propagation behavior of propane–air premixed combustion in a confined space with two perforated plates at different initial pressures

open access: yesEnergy Science & Engineering, 2022
The aim of this paper is to analyze local autoignition induced by secondary flame acceleration. The secondary flame acceleration process and the local autoignition formation mechanism at the condition of the secondary flame acceleration propagation were ...

Hydrogen jet flames [PDF]

open access: yesInternational 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,

Flow and Temperature Characteristics of a 15° Backward-Inclined Jet Flame in Crossflow

open access: yesEnergies, 2018
The flow and flame characteristics of a 15° backward-inclined jet flame in crossflow were investigated in a wind tunnel. The flow structures, flame behaviors, and temperature fields were measured.

Modelling and control of the flame temperature distribution using probability density function shaping [PDF]

open access: yes, 2006
This paper presents three control algorithms for the output probability density function (PDF) control of the 2D and 3D flame distribution systems. For the 2D flame distribution systems, control methods for both static and dynamic flame systems are ...

Investigation for Effects of Jet Scale on Flame Stabilization in Scramjet Combustor

open access: yesEnergies, 2022
Jet scale affects the mixing and combustion of fuel and inflow. With the increase in the scale of scramjet combustors, the study of large-scale jets is particularly significant.

LIFTED LAMINAR JET DIFFUSION FLAMES [PDF]

open access: yesCombustion 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

open access: yesNihon 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

open access: yesEnergies, 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 ...
