Bunsen 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...
متن کاملFast, Adaptively Refined Computational Elements in 3D
We describe a multilevel adaptive grid refinement package designed to provide a high performance, serial or parallel patch class for use in PDE solvers. We provide a high level description algorithmically with mathematical motivation. The C++ code uses cache aware data structures and automatically load balances.
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 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...
