Laser Induced Incandescence for Volume Fraction and Relative Particle Size Measurements in a Rich-Quench-Lean Jet A Combustor
… (LII) diagnostics inside a three-sector rich-quench-lean (RQL) aeroengine combustor running with Jet A fuel. First, the setup is described including details of the combustor, pressure vessel, data acquisition system, optics, and facilities. Then, the methodology for calibrating and …

Experimental Investigation of Large Scale Aerodynamics on Soot Emissions in Swirling Flows
… emissions standards. Modern burners utilize the Rich-Quench-Lean (RQL) technology that employs turbulent swirling flames with downstream dilution air. These turbulent flames exhibit spatial and temporal fluctuations not present in laminar flames. This adds a level of complexity to turbulent soot …

An Experimental Investigation of Self-Excited Combustion Dynamics in a Single Element Lean Direct Injection (LDI) Combustor
… have led to engine operation in a narrow, lean regime. While premixed or partially premixed combustor configurations such as the Lean Premixed Pre-vaporized (LPP), Rich Quench Lean burn (RQL), and Lean Direct Injection (LDI) have shown a potential for reduced NOx emissions, they promote a …

Predicting Soot Emissions with Advanced Turbulent Reacting Flow Modelling
… is simulated to explore soot PSD evolution in a Rich-Quench-Lean (RQL) burner configuration widely used in practice for emissions control. Results show a reasonably good agreement with experiments for the mean reaction zone and soot locations and their variations with different airflow provided …
