Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

open access: yesEnergy Science &Engineering, EarlyView.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

EFFECT OF OXYGEN ENRICHMENT UPON LAMINAR BURNING VELOCITY OF (BUTANE – O2 – N2) MIXTURE

open access: yesJournal of Engineering and Sustainable Development, 2016
The effect of oxygen enrichment on the laminar flame speed of (butane – oxygen – nitrogen) premixed mixture. The measurement system is designed to measure the laminar flame speed using a tube – method and optical technique (photodiode).The laminar flame

Role of pocket formation in the extinction of methane flames subject to strong turbulence

open access: yesApplications in Energy and Combustion Science
Despite extensive studies of local and global extinction, it remains unclear how local flame dynamics contribute to the global evolution of a turbulent flame at large Karlovitz numbers. Furthermore, the extent to which canonical laminar flame properties,

Flame theory and combustion technology [PDF]

open access: yes, 1956
The study of combustion processes is in a sufficiently early stage so that there is no strong connection between combustion theory and the technology of combustion chamber development.

Measurements of Laminar Flame Speeds of Alternative Gaseous Fuel Mixtures

open access: yesJournal of Energy Resources Technology, 2015
Global warming and the ever increasing emission levels of combustion engines have forced the engine manufacturers to look for alternative fuels for high engine performance and low emissions. Gaseous fuel mixtures such as biogas, syngas, and liquefied petroleum gas (LPG) are new alternative fuels that have great potential to be used with combustion ...

Transient combustion modeling of an oscillating lean premixed methane/air flame [PDF]

open access: yes, 2008
The main objective of the present study is to demonstrate accurate low frequency transient turbulent combustion modeling. For accurate flame dynamics some improvements were made to the standard TFC combustion model for lean premixed combustion.

Influence of Adhesive Type on Heat Induced Delamination in Tension Loaded Shear Lap Cross‐Laminated Timber Samples Exposed to Radiant Heat Flux

open access: yesFire and Materials, EarlyView.
ABSTRACT Heat induced delamination (HID) is a phenomenon in engineered wood products which may result in the detachment of the bonded timber lamellae before charring propagates to the bond line interphase. This study aims to correlate the thermal degradation of two 1‐c‐polyurethane adhesives at the microscale to the thermo‐hydro‐mechanical behaviour of

Laminar Flame Characteristics of Premixed Methanol–Water–Air Mixture

open access: yesEnergies, 2020
Methanol is hygroscopic in a gaseous state and is a promising alternative fuel for internal combustion engines. It is understood that adding water can improve the antiknock performance for spark ignition engines, but this will also affect the flame speed
