Effect of Air Jet Splitting on the Elliptical Burner Inverse Diffusion Flame Characteristics: A Computational Study

This computational study explores the effects of air jet splitting on the combustion characteristics of elliptical burner inverse diffusion flames (IDFs).The paper focuses on the impact of increasing the number of central air jets on flame aerodynamics, temperature distribution, and pollutant emissions.The study utilizes ANSYS CFX 2022 R1 software for simulation to examine configurations with single, double, and triple air jets while maintaining constant thermal input and inlet velocities.Results indicated that air jet splitting enhances fuel-air mixing, reduces soot formation, and optimizes combustion efficiency.There was a notable impact on the temperature distribution within the flame and on the concentrations of pollutants emitted.The results enhance our comprehension of IDFs with elliptical jets, highlighting their potential utility in energy and thermal processes.This work underscores the significance of jet interaction and aerodynamics in advancing the IDF combustion technology for sustainable utilization.
