“…Wang et al [12] suggested a new reaction mechanism with 50 components to predict soot emission by predicting important soot precursor species such as C 2 H 2 , C 2 H 4 , and C 6 H 6 . They showed that CFD simulation of an air assisted flare with this mechanism better predicted soot emission from the flare.…”

Computational fluid dynamics (CFD) was used to simulate multi tip flare system with different operating conditions during ignition time. Single tip and three tips flare systems were simulated and verified against experimental test to get CFD combustion model that required for multi tip flare system. Natural gas, propane, propylene, ethylene and xylene were used as flaring gases in simulated tests of single and three tips flare under an open environment that carried out at the Zeeco facility in Tulsa, OK. This study aimed to predict the soot formation and heat radiation from full multi tip flare field by using CFD modeling with verified combustion model and large eddies simulation (LES) turbulence model with a reduced four step combustion mechanism. The results showed that the multi tip flare system performance can be predicted by using C3d tool.

“…Although many studies and fundamental research efforts aim to increase the understanding of soot formation mechanisms, combining detailed combustion mechanisms with realistic flow field to capture the effects of choices made in the numerical model on soot inception, growth, and oxidation has seldom been done. Verification of the models is mainly done comparing ignition delay and flame speed in zero- or one-dimensional models and the experiments. ,− Gas mixtures encountered in syngas and biogas conversion processes are rarely considered in soot studies, and research efforts are needed to assess the capabilities of available numerical tools. , …”

Experimental and Numerical Investigation of Flow Field and Soot Particle Size Distribution of Methane-Containing Gas Mixtures in a Swirling Burner

The formation of soot in a swirling flow is investigated experimentally and numerically in the context of biogas combustion using a CO 2 -diluted methane/oxygen flame. Visualization of the swirling flow field and characterization of the burner geometry is obtained through PIV measurements. The soot particle size distributions under different fuel concentrations and swirling conditions are measured, revealing an overall reduction of soot concentration and smaller particle sizes with increasing swirling intensities and leaner flames. An axisymmetric two-dimensional CFD model, including a detailed combustion reaction mechanism and soot formation submodel, was implemented using a commercial computational fluid dynamics (CFD) code (Ansys Fluent). The results are compared with the experiments, with similar trends observed for the soot size distribution under fuel-lean conditions. However, the model is not accurate enough to capture soot formation in fuel-rich combustion cases. In general, soot particle sizes from the model are much smaller than those observed in the experiments, with possible reasons being the inappropriate modeling in Fluent of governing mechanisms for soot agglomeration, growth, and oxidation for CH 4 -CO 2 mixtures.
