Flamelet Characteristics of Gaseous and Spray Lifted Flames on Two-Dimensional Direct Numerical Simulations

open access: yesJournal of Fluid Science and Technology, 2008
The detailed behaviors of gaseous and spray lifted flames are studied by two- dimensional direct numerical simulations (DNS), and the characteristics of the flamelets are investigated in terms of two key variables for flamelet modeling, namely mixture ...

Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner

open access: yesJournal of Thermal Science and Technology, 2018
Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...

Growth and Oxidation of Graphitic Crystallites in Soot Particles within a Laminar Diffusion Flame [PDF]

open access: yes, 2014
The growth and oxidation behaviors of graphitic crystallites in soot particles within a laminar co-flow propane diffusion flame were investigated experimentally. Soot was sampled along the flame axis and collected on a quartz?fiber filter.

The Effects of Differential Diffusion on Turbulent Non-Premixed Flames LO2/CH4 under Transcritical Conditions Using Large-Eddy Simulation

open access: yesEnergies, 2023
In this paper, a large-eddy simulation (LES) of turbulent non-premixed LO2/CH4 combustion under transcritical conditions is performed based on the Mascotte test rig from the Office National d’Etudes et de Recherches Ae´rospatiales (ONERA), and the aim is

Measurement of temperature and velocity fluctuations in a turbulent diffusion flame by an optical fiber thermometer and a laser 2-focus velocimeter [PDF]

open access: yes, 1997
Both fluctuations of local velocity and local temperature were measured in a steady turbulent diffusion flame of propane by using the semiconductor laser 2-focus velocimeter (L2F) and the optical fiber thermometer (OFT) respectively.

Study on flame stability in oxygen-enriched ammonia/N2/O2 laminar diffusion flame

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Ammonia is regarded as one of the alternative fuels because CO2 is not emitted during the combustion process of ammonia. The physical properties of ammonia are suitable for transportation and storage as a “hydrogen carrier”.

Wavelet based flickering flame detector using differential PIR sensors [PDF]

open access: yes, 2011
A Pyro-electric Infrared (PIR) sensor based flame detection system is proposed using a Markovian decision algorithm. A differential PIR sensor is only sensitive to sudden temperature variations within its viewing range and it produces a time-varying ...
