Numerical Investigation of Forced Ignition in Laminar Counterflow Non- Premixed Methane-air Flames
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 instantaneous heat release in an inert mixing layer. Ignition success depends on the mixture composition at the spark location, resulting in lea...
متن کاملInhibition of Premixed Methane-air Flames by Iron Pentacarbonyl
Introduction: Brorninated fwe suppressants are effective and widely used [1]. Due to their destruction of stratospheric ozone, however, the production of these chemicals was halted in January 1994. Although testing and development of possible substitutes is occurring [2], a repkcement with all of the desirable properdes of CF3Br (the most common fire suppressant) has yet to be identified. Conse...
متن کاملOptical Emission Tomography of Non-axisymmetric, Laminar, Premixed Flames
Optical emission tomography of flames has recently been demonstrated as a practical experimental technique for determining the instantaneous position of a 3D flame surface. In this paper, optical emission tomography is applied to steady and forced, non-axisymmetric, premixed, laminar flames. An experimental set-up involving a single camera and a rotatable flame holder allows camera images from ...
متن کاملChemically-Passive Suppression of Laminar Premixed Hydrogen Flames in Microgravity
Effects of chemically-passive fire suppressants on laminar premixed hydrogen flames were investigated by combined use of microgravity experiments and computations. The experiments used a short-drop free-fall laboratory facility that provides at least 450 ms of 2 10 g. Near -limit laminar burning velocities were measured for outwardly propagating spherical stoichiometric hydrogen-air flames with...
متن کاملEquivalence Ratio Effects in Turbulent, Premixed Methane-air Flames
Turbulent methane flames exhibit a change in Markstein number as the equivalence ratio changes. In this paper, we demonstrate how these changes in Markstein number are related to shifts in the chemistry and transport. We focus on the analysis of simulations of two-dimensional premixed turbulent methane flames at equivalence ratios φ=0.55 and φ=1.00 computed using the GRI-Mech 3.0 mechanism. The...
