NUMERICAL SIMULATION OF HIGH PRESSURE BURNER WITH PARTIALLY PREMIXED FLAME
CT&F Ciencia, Tecnología & Futuro, 2011 In this paper we present the results of a 2D axisymmetric parametric study which simulates an atmospheric premixed burner with flame at high pressure, in which methane is burned.

Experimental Characterisation of Swirl Stabilized Annular Stratified Flames [PDF]
, 2007 A burner for investigating lean stratified premixed flames propagating in intense isotropic turbulence has been developed. Lean pre-mixtures of methane at different equivalence ratios are divided between two concentric co-flows to obtain annular ...

A Lagrangian-based flame index for the transported probability density function method
Theoretical and Applied Mechanics Letters, 2022 We propose a new flame index for the transported probability density function (PDF) method. The flame index uses mixing flux projections of Lagrangian particles on mixture fraction and progress variable directions as the metrics to identify the ...

Large Eddy Simulation of Partially Premixed Flame with Local Extinction Phenomenon
Shanghai Jiaotong Daxue xuebao, 2022 The Sydney partially premixed flame FJ200-5GP-Lr75-103 case with the local extinction phenomenon is studied by large eddy simulation (LES) coupled with the dynamic k equation sub-grid scale model and the dynamic thickened flame (DTF) combustion model. To

A Method to Image Flame Index in Partially Premixed Flames [PDF]
50th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2012 This paper describes a new method to image the flame index in partially premixed flames. To improve modeling of partially premixed flames, such as those in gas turbines and scramjets, there is a need to measure the flame index. CHEMKIN modeling of both premixed and non-premixed methane (CH4) / air flames determined that acetone (CH3COCH3) and nitrogen ...
