Large Eddy Simulation of a Swirl-Stabilized Pilot Combustor from Conventional to Flameless Mode

Journal of Combustion, 2016
This paper investigates flame and flow structure of a swirl-stabilized pilot combustor in conventional, high temperature, and flameless modes by means of a partially stirred reactor combustion model to provide a better insight into designing lean ...

Effects of Turbulence on the Combustion Properties of Partially Premixed Flames of Canola Methyl Ester and Diesel Blends

Journal of Combustion, 2011
Canola methyl ester (CME) is a biofuel that is a renewable alternative energy resource and is produced by the transesterification of canola oil. The objective of this study was to document the effects of turbulence on the combustion characteristics of ...

Combustion mechanism of propane-air swirling premixed flame near lean flammability limit

Journal of Thermal Science and Technology
This study investigated a premixed propane-air flame in a partially tapered swirl burner. Experimentally, we found that a flame resembling a morning glory flower formed at an equivalence ratio near the lean flammability limit.

Improved combustion stability of biogas at different CO2 concentrations using inhomogeneous partially premixed stratified flames

Global Energy Interconnection
Biogas is a renewable and clean energy source that plays an important role in the current environment of low- carbon transition. If high-content CO2 in biogas can be separated, transformed, and utilized, it not only realizes high-value utilization of ...

Numerical investigation of forced ignition in laminar counterflow non-premixed methane-air flames

, 2007
Simulations of forced ignition of non-premixed laminar counterflow flames are used to study the effect of strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics and treating the spark as an ...

Numerical Simulation of Swirl and Methane Equivalence Ratio Effects on Premixed Turbulent Flames and NOx Apparitions

Journal of Applied Fluid Mechanics, 2016
This paper presents a three dimensional numerical simulation of premixed methane-air low swirl stabilized flames. The computational domain has a simple geometry describing a LBS (low swirl burner) with 50mm of nozzle diameter. RANS Standard κ – ε model
