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.

Energies, 2021 The length and pattern of air–fuel mixing plays a significant role in the uniformity, flame temperature, and emission characteristics, which can lead to a superior product quality in a non-oxidizing direct fired burner for a cold-rolled steel plate ...

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 ...

An experimental study on coflow diffusion combustion in a pellet-packed bed with different bed lengths [PDF]
Royal Society Open Science, 2018 In experimental investigations on axial symmetry, over-ventilated CH4/air diffusion combustion in a packed bed is executed to study the height, shape and stability of the flame.

Lifted Partially Premixed Flames in Microgravity [PDF]
42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004 Lifted Double and Triple flames are established in the UIC-NASA Partially Premixed microgravity rig. The flames examined in this paper are established above a coannular burner because its axisymmetric geometry allows for future implementation of other non-intrusive optical diagnostic techniques easily.

A novel diffusion flux modeling for laminar premixed flame simulation with OpenFOAM
Results in Engineering, 2023 In this study, we developed a mass diffusion coefficient model for premixed combustion to reduce the computational time, in mixture-averaged diffusivities to serve as a microcomputer resource.
