Ignis: A one-dimensional laminar flame code

SoftwareX
Laminar flame codes have an important role in combustion modeling. They can provide a fundamental understanding of flame dynamics and provide a basis for building subgrid scale models in turbulent flow simulations.

Fluid-mechanical structure of methane-air and propane-air turbulent premixed flames

Nihon Kikai Gakkai ronbunshu, 2015
The flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic of turbulence have been closely examined by using a three-color six-beam LDV system.

Towards detailed combustion characteristics and linear stability analysis of premixed ammonia‒hydrogen‒air mixtures

Applications in Energy and Combustion Science
In this study, premixed ammonia‒hydrogen‒air mixtures at different pressures (50∼300 kPa), equivalence ratios (0.7∼1.5), and hydrogen concentrations (9∼50.00 %) were centrally ignited in a closed vessel, and the propagation of a spherical flame was ...

Pulsed TV holography and schlieren studies, and large eddy simulations of a turbulent jet diffusion flame

, 2004
In the search for an improved understanding of jet-flame dynamics we here compare predictions from large-eddy simulations (LES) and measurements using schlieren and holographic interferometry of a round turbulent jet diffusion flame.

Wind-aided flame spread under oblique forced flow

, 1999
he wind-aided flame spread process along a solid fuel rod under oblique forced flow is analyzed in absence of gravity or when the forced flow dominates the gravity-induced flow.

Experimental Investigation of the Continuous Transition of Flame-Spreading near the Blow-Off Limit

Journal of Combustion, 2020
This study investigates the continuous transition from flame-spreading to stabilized combustion near the blow-off limit in opposed forced flow by using expanding solid fuel duct that makes distribution of oxidizer velocity in the axial direction.

Multicomponent Fuel Diffusion Flames: Flame Structure for Coupled Diffusion-Flame and Premixed-Flame Burning Regimes

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
The analysis addresses some aspects of the extinction and the structure of diusion flames established by burning of two fuels. This analysis is asymptotically performed presuming one-global-step chemical reactions with large activation energies. By working with fuels with dierent activation energies, the structure is composed by two zones with dierent ...

A simultaneous non-invasive diagnosis method for flame temperature and velocity fields based on radiation self-calibration and optical flow

Case Studies in Thermal Engineering
The measurement of flame temperature and velocity is crucial to combustion research, hence it is of great significance to develop a non-invasive diagnosis technology for the measurement of flame temperature and velocity.
