Validating Confined Flame Noise Simulation Using External Sensor [PDF]
Sensors, 2022 Advancements in lean premixed combustion have increased the efficiency and reduced the amount of greenhouse gas emissions, but they have led to increased noise emissions due to higher turbulence and mixing fluctuations. This study used an external sensor

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 ...

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 ...

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.
