Investigation of Air Turbulence Intensity Effect on the Flame Structure in Different Flame Holder Geometry
In this paper, the effect of air turbulence intensity on the flame structure in various radii and lengths of a flame holder numerically studied. Finite volume method is used to solve the governing equations. The obtained numerical results using realizable k-ε and β-PDF models show a good agreement with the experimental data. The results show that flame holder with greater lengths yield shorter ...
متن کاملThe Effect of a Flame Holder Shape Modification Toward the Diffusion Flame Stability Zone Shift
The flame stability limit, which was involving the critical flow condition, lift off and blow out, could be affected by the burner geometry in the combustion system installation. Consequently a flame holder should be put in, to hold the flame as big as possible on a stable condition. The flame holder itself, is a device to hold the flame, whereas the flame holder could disturb the air and fuel ...
متن کاملOn Generalized Holder Inequality
A FAMILY of inequalities concerning inner products of vectors and functions began with Cauchy. The extensions and generalizations later led to the inequalities of Schwarz, Minkowski and Holder. The well known Holder inequality involves the inner product of vectors measured by Minkowski norms. In this paper, another step of extension is taken so that a Holder type inequality may apply to general...
متن کاملNumerical investigation of plasma / flame interactions
Flame ignition or extinction is the result of very complex interactions between combustion chemistry and turbulence. It has been recently observed in experimental studies [1,2] that the presence of a plasma discharge in the vicinity of reaction zones affects combustion. For instance, a discharge generated in a combustion chamber produces a pool of radicals. These highly reactive species strongl...
متن کاملAn investigation of Rubens flame tube resonances.
The Rubens flame tube is a century-old teaching demonstration that allows observers to visualize acoustic standing wave behavior [H. Rubens and O. Krigar-Menzel, (1905). Ann. Phys. 17, 149-164]. Flammable gas inside the tube flows through holes drilled along the top, and flames are then lit above. The tube is closed at one end and driven with a loudspeaker at the other end. When the tube is dri...
