effect of tip diameter on soot formation in an industrial flare

Soot formation in industrial flares is a critical environmental issue, and is affected by various parameters and factors# tip diameter changes can cause variations in some of these decisive factors; therefore it is necessary to study the effects of tip diameter# in this study, cfd model for an industrial flare is developed in ansys fluent software, and the validation study of that is done by comparing the results to the experimental data of a lab-scale flare# the focus of the study is on turbulence characteristics and available contact surface area, according to the results, soot yield increases by increasing tip diameter, and the turbulence of flame is not useful in soot reduction without making a larger contact surface for air/fuel mixing#
