Infrared 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 کاملInvestigation 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 کاملFlame Stability and Structure of Liquefied Petroleum Gas-Fired Inverse Diffusion Flame with Hydrogen Enrichment
The present project was conducted with the circumferential-fuel-jets inverse diffusion flame (CIDF) burner burning liquefied petroleum gas (LPG) enriched with 50% of hydrogen fuel (H2). The range of stable operation of the CIDF burner in terms of Reynolds number (from laminar to turbulent flow regions), equivalence ratio and fuel jet velocity of LPG of the 50% H2-LPG mixed fuel was identified. ...
متن کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولBunsen flame simulation by finite elements on adaptively refined, unstructured triangulations
We investigate laminar Bunsen flames with detailed chemistry and multicomponent transport. The governing equations are discretized by a finite element method on a sequence of adaptively refined, unstructured triangulations. The finite element method is an extension to chemically reacting flows of the streamline diffusion method, including least-squares stabilization of the pressure gradient and...
