Numerical and experimental study of no emission in laminar partially premixed flames

Proceedings of the Combustion Institute, 2000
A partially premixed methane/air flame in a two-dimensional configuration was studied in this work. The configuration was close to those used in real domestic boilers. The flame structure and flow pattern were calculated by implementing a complex chemistry and detailed transport formulation in an industrial computational fluid dynamics code (ESTET).

A numerical investigation of the flame structure of an unsteady inverse partially premixed flame

Combustion and Flame, 1997
Abstract The flame structure of unsteady flickering partially premixed flames is numerically investigated, and detailed results are provided for a flame established at Fr = 0.5, Re = 500, and overall Φ = 1. A numerical study is conducted in an inverse configuration in which a fuel-rich (CH4-air) annular jet is sandwiched between an axisymmetric air ...

LaminarTriple Flames in Partially Premixed Opposed Flows

Combustion Science and Technology, 1998
Presented is an asymptotic analysis of premixed laminar flames in opposed streams under circumstances of fast chemistry and/or low rates of strain and of high Reynolds numbers. In this case there exist three distinct reaction layers, two premixed and one nonpremixed, the latter centered on the stagnation plane.

Premixed and Partial Premixed Turbulent Flames at High Reynolds Number

2018
Methane/air premixed and partially premixed turbulent flames at high Reynolds number are characterized using Direct Numerical Simulations (DNS) with detailed chemistry in a spatially evolving slot Bunsen configuration. Two sets of simulations are performed. A first set of simulations with fully premixed inlet conditions is considered in order to assess

Partially Premixed Laminar Gas Flames from Triangular Burners

Journal of Propulsion and Power, 1996
An experimental study of the effects of using triangular burner exit ports in place of the standard circular ports in a laminar partially premixed gas burner is presented. A natural gas burner employed in a small residential-scale heating system rated at 5.86 kW was modie ed. Air entrainment into the nonburning jets, emission indices of nitrogen oxides
