Effects of Flow Transients on the Burning Velocity of Laminar Hydrogen/air Premixed Flames
The effects of unsteady strain rate on the burning velocity of hydrogen/air premixed flames have been studied in an opposed nozzle configuration. The numerical method employs adaptive time integration of a system of differential–algebraic equations. Detailed hydrogen/air kinetic mechanism and transport properties are considered. The equivalence ratio is varied from lean to rich premixtures in o...
متن کاملNear-limit laminar burning velocities of microgravity premixed hydrogen flames with chemically-passive fire suppressants
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 freefall laboratory facility that provides at least 450 ms of 10 2 g. Near-limit laminar burning velocities were measured for outwardly propagating spherical stoichiometric hydrogen-air flames with v...
متن کاملExperimental study of pollutants formation in laminar premixed flames of tetrahydrofuran family fuels
To better understand the combustion chemistry of tetrahydrofuran (THF) and 2-methyltetrahydrofuran (MTHF) which has been considered as promising bio-fuel, the structure of their stoichiometric (φ=1.0) low-pressure laminar premixed flame has been investigated. The flames have been stabilized on a burner at a pressure of 50 Torr (6.7 kPa) using argon as dilutant (78 %), with a gas velocity at the...
متن کاملGravity effects on partially premixed flames: an experimental-numerical investigation
While premixed and nonpremixed microgravity flames have been extensively investigated, the corresponding literature regarding partially premixed flames (PPFs) is sparse. We report the first experimental investigation of burner-stabilized microgravity PPFs. Partially premixed flames with multiple reaction zones are established in microgravity on a Wolfhard–Parker slot burner in the 2.2 s drop to...
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 ...
