Cellularization characteristics of ethyl acetate spherical expanding flame

Fuel, 2021
Abstract The cellular instability of ethyl acetate (EA) premixed flame has been studied theoretically and experimentally under different initial temperature, pressure and equivalence ratio. The constant pressure method (CPM) was used to determine the laminar burning velocity of EA spherical expanding flame in this research.

Wrinkling of spherically expanding flames

Proceedings of the Combustion Institute, 2002
The onset of instability and subsequent development of cells on spherically expanding flames is examined theoretically. The model used accounts for both hydronamic and diffusive-thermal effects and, in contrast to earlier theories, is valid for variable transport properties over a wide range of equivalence ratios.

Cellularization of 2-methylfuran expanding spherical flame

Combustion and Flame, 2019
Abstract Flame instabilities in 2-methylfuran (MF) outwardly propagating laminar flames have been investigated experimentally and theoretically at the initial pressures of 1–4 bar, temperatures of 363–423 K and equivalence ratios of 0.7–1.4. The flame topography and the effects of flame instability on MF burning speeds have been examined.

Extrapolations of laminar flame speeds from expanding spherical flames based on the finite-structure stretched flames

Combustion and Flame, 2021
Abstract The modified models MLC (modified linear curvature model) and MNQ (modified nonlinear quasi-steady model) for the extrapolation of laminar flame speeds and Markstein lengths based on the expansion of the finite-structure stretched flames were derived from the mass conservation equation, which consider effects of finite flame thickness and ...

Flame morphology and self-acceleration of syngas spherically expanding flames

International Journal of Hydrogen Energy, 2018
Abstract The self-acceleration of spherically expanding flames were investigated using a constant volume combustion chamber for CO/H2/O2/N2 mixtures over a wide range of initial pressure from 0.2 to 0.6 MPa, CO/H2 ratio from 50/50 to 10/90 and equivalence ratio from 0.4 to 1.5.

Cellular Instabilities in Spherically Expanding Hydrogen-Oxygen-Carbon Dioxide Flames

ASME 2023 ICE Forward Conference, 2023
Abstract Hydrogen (H2) has several properties that make it a promising alternative fuel. It is carbon-free, has a high gravimetric energy density, and can be compatible with some existing conversion technologies. However, there are several challenges in its large-scale use, such as a high flammability envelope and fundamentally different

Uncertainty reduction in laminar flame speed extrapolation for expanding spherical flames

Combustion and Flame, 2018
Abstract The quantification and reduction of the uncertainties in the extrapolation process in laminar flame speed measurements were studied using expanding spherical flames under positive Markstein length (Lb> 0) conditions. The experimental and computational results were first compared showing their differences.

Transition to detonation of an expanding spherical flame

Combustion and Flame, 2017
Abstract With a freely expanding unwrinkled spherical flame as an example, it is shown that deflagration-to-detonation transition in unconfined gaseous systems is possible, provided the flame is close to its propagability threshold and the deficient reactant Lewis number is not too small.

Markstein lengths of CO/H2/air flames, using expanding spherical flames

Symposium (International) on Combustion, 1996
Markstein lengths (defined as the reduction in burning velocity per unit stretch) have been measured for a series of CO/H2/air flames at atmospheric pressure. Values as a function of stoichiometry are reported for three fuels (95%/5% CO/H2, 50%/50% CO/H2, and 100% H2).
