Numerical simulation of high pressure burner with partially premixed flame

CT&F - Ciencia, Tecnología y Futuro, 2011
In this paper we present the results of a 2D‑axisymmetric parametric study which simulates an atmospheric premixed burner with flame at high pressure, in which methane is burned. A total of 9 simulations are performed with different regulators openings of primary and secondary air.

Two recent developments in numerical simulation of premixed and partially premixed turbulent flames

Comptes Rendus. Mécanique, 2006
A subgrid scale closure for Large Eddy Simulation of premixed turbulent combustion (FSD-PDF) is proposed. It combines the Flame Surface Density (FSD) approach with a presumed Probability Density Function (PDF) of the progress variable that is used in flamelet chemistry tabulation.

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.

Effects of Equivalence Ratio and Inlet Temperature on Combustion and NO_x Emissions of Partially Cracked Ammonia in a Cavity Micro-Combustor

Energies
This work numerically examines the premixed combustion of partially cracked ammonia/air in a cavity-stabilized micro-combustor. Effects of the equivalence ratio (Φ) and inlet temperature (Tin) on the combustion features, flame–wall heat transfer and ...

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

COMPARACIÓN DEL MUESTREO DE ESPECIES QUÍMICAS EN ZONAS REACTIVAS MEDIANTE EL USO DE SONDA CON Y SIN CUELLO SÓNICO COMPARISON OF SAMPLING CHEMICAL SPECIES IN REACTING ZONES USING PROBES WITHOUT SONIC NOZZLE

Ingeniare: Revista Chilena de Ingeniería, 2010
El análisis de los productos de combustión en las zonas de reacción y al interior de cámaras de combustión requiere, con respecto a las medidas efectuadas en chimeneas, de equipos y de métodos particulares de muestreo. Así por ejemplo, en las zonas donde
