Investigation of Bunsen flame dynamics by the method of characteristics
Understanding the dynamics and the stabilisation of flames is important for practical applications and for theoretical research. Here, to investigate the time-evolution of a Bunsen flame in a Poiseuille flow, we extend a G-equation-based kinematic model by accounting for flame stabilisation. The nonlinear G-equation is solved analytically using the methods of characteristics. The solution is th...
متن کاملInfrared radiation from a Bunsen flame.
Many observers have studied th e infrared emi sion of a Bunsen flame [11. 2 The strongest band ocem s at about 4.4 Il and is produced by carbon dioxid e. Other bands have been found a t 0.95, 1.45, 2.0, and 2.8 Il , and are a ttributed to carbon dioxide and water vapor. Very little radiation has been observed in the region beyond 7 Il . In the visible and ultraviolet regions of the spectrum, co...
متن کاملSimulation of Nitrogen Emissions in a Premixed Hydrogen Flame Stabilized on a Low Swirl Burner
There is considerable interest in developing fuel-flexible, low emissions turbines for power generation. One approach is based on burning a variety of lean premixed fuels with relatively low flame temperatures. Such flames can be stabilized in a low swirl burner configuration, for example, using a variety of fuels such as pure hydrogen and hydrogen-seeded hydrocarbon mixtures. However, many hyd...
متن کاملApplication of a Flame Dictionary Method in Turbulent Premixed Flame Modeling. Construction of a Flame Dictionary
|The construction of a ame dictionary of ame speeds and preheat thicknesses for a given reaction will be discussed. Once the entries of the dictionary have been established, they can be accessed by researchers and programmers to be used in diierent combustion applications. An application of the ame dictionary for turbulent combustion in a circular cylinder is given. Chemical reactions are often...
متن کاملEffects of Flame Temperature on Combustion Instabilities of a Premixed Burner
Combustion instabilities in gas turbine has been a major setback in the quest for efficient and clean combustion. Accurate characterisation and prediction of these disturbances is required to suppress them either at the design stage or in a close loop control when the system is in operation. The use of flame transfer functions has been a common approach in different literatures. Flame temperatu...
