Characteristics of Flame Bases for V-Gutters Stabilized Premixed Flames
Volume 8A: Heat Transfer and Thermal Engineering, 2013The objective of this work is to investigate the flame stabilization mechanism and the impact of the operating conditions on the characteristics of the steady, lean premixed flames. It’s well known that the flame base is very important to the existence of a flame, such as the flame after a V-gutter, which is typically used in ramjet and turbojet or ...

An Experimental Study on Flame Characteristics of Hydrogen Diffusion Flames [PDF]
, 1993 An experimental study has been performed on hydrogen jet diffusion flames from vertical circular nozzles burning in free air. The direct photographic method was employed to investigate the influence of fuel flow rate and nozzle diameter, d, on the flame morphology.

On the Flame and Vorticity Characteristics of a Fluidically Stabilized Premixed Turbulent Flame
48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010Flame stabilization is the act of maintaining combustion in the presence of a high-speed premixed flow, and continues to be an important process that influences the performance and limitations for propulsion applications. A common approach for current generation flame holders involves the employment of a low-speed recirculation zone where hot ...

Dynamic characteristics of flame fronts in a turbulent premixed flame zone
Symposium (International) on Combustion, 1985Instantaneous local flame front movements in the flame zone of a turbulent premixed burner flame have been examined using a micro-electrostatic probe with three sensors. Based on the measured values of the instantaneous inclined angle and velocity of the local flame front, frequency distributions at representative locations in the flame zone were ...

Flame speed characteristics of turbulent expanding flames in a rectangular channel
Combustion and Flame, 2019Abstract We present results from studies of freely expanding flames in a unique small-scale convective facility for different free-stream initial conditions, characterized by Taylor-Reynolds numbers in the range of R e λ g = 179 − 395 (using the streamwise RMS velocity component and the lateral Taylor-microscale) and an inertial ...

A theoretical study of flame properties as a function of the characteristics of flame gases
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1966Abstract Part I General equations are presented for a method of calculating the net rate of production and the fractional mass-flow rate for each species without introducing the kinetic steady-state approximation. Mathematical problems of smoothness and stability which must be surmounted in any method which avoids the kinetic steady ...

Numerical Study of Buoyancy and Flame Characteristics of Ammonia-Air Flames
ASME 2024 ICE Forward ConferenceAbstract There is growing interest in ammonia, NH3, as a zero-carbon fuel for use in transportation as part of broader decarbonization efforts. Ammonia has several advantages as an alternative fuel, including an existing global infrastructure and the ability to be stored as a liquid at room temperature and moderate pressures, thereby ...
