Potential model of a two-dimensional Bunsen flame

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...

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...

A two-dimensional numerical model of a planar solid oxide fuel cell

A two-dimensional CFD model of a planar solid oxide fuel cell (SOFC) has been developed.This model can predict the performance of SOFC at various operating and design conditions.The effect of Knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. The mathematical model solves conservation of electrons and ions and conservation ofspecies. The model is formulate...

STATISTICAL-MECHANICAL CALCULATION OF THERMODYNAMIC PROPERTIES OF ALBITE USING A TWO-DIMENSIONAL MODEL

Can a One-dimensional Strained Flame Model Combustion in Flame-vortex Interactions?

We present a study of the flame-embedding concept, introduced in [1] as an efficient approach for large-eddy simulation of turbulent combustion at high Reynolds and Damköhler numbers. In flame embedding, the combustion zone is modeled as an unsteady flame modified by the local tangential strain rate, with the latter extracted every time step from the flow field simulations. The flame structure ...
