Flame Structure Interactions and State Relationships in an Unsteady Partially Premixed Flame
In this investigation our objective is 1) to compare the similitude between an unsteady, two-dimensional (axisymmetric), partially premixed ame and an analogous steady, partially premixed amelet to determine if state relationshipsin terms ofamodi ed conserved scalar applyand2) to investigate amestructure interactionsbetween the various reaction zones contained in partially premixed ames...
متن کاملHeat Transfer Effects on a Fully Premixed Methane Impinging Flame
The effects of heat transfer on engineering applications is a fundamental aspect in the design of power and propulsive systems. The heat exchange between fluid and solid parts may reduce the efficiency of the system in situations where temperature peaks and gradients become important. This is the case of gas turbines, combustion engines or cooling of turbine blades. However, this interaction is...
متن کاملCeramic panel heating under impinging methane-air premixed flame jets
Due to the ever wider use of composite materials within aerospace applications, fireproof tests get recently an increased attention. Numerical simulation is expected in the coming years to accompany engineers in their design work to increase the chance of success in the fireproof certification tests. The current research focuses on the numerical investigation of a premixed methane-air flame imp...
متن کاملA Computational Study of the Soot Formation in Methane-Air Diffusion Flame During Early Transience Following Ignition
act— A CFD-based numerical model has been ed for the determination of the volume concentration ber density of soot in a laminar diffusion flame of in air, under transient condition following ignition of e. The transience is studied from the point of ignition final steady state is reached. The burner is an axiric co-flowing one with the fuel issuing through a port and air through an annular port...
متن کاملPremixed-flame shapes and polynomials
The nonlinear nonlocal Michelson-Sivashinsky equation for isolated crests of unstable flames is studied, using pole-decompositions as starting point. Polynomials encoding the numerically computed 2N flame-slope poles, and auxiliary ones, are found to closely follow a MeixnerPollaczek recurrence; accurate steady crest shapes ensue for N3. Squeezed crests ruled by a discretized Burgers equation ...
