“…1−5 Most of these studies are summarized in the review papers of Margason 6 and Mahesh. 7 One of the recent studies on gas jet impingement in crossflow was performed by Kartaev et al 2 to investigate the impact of the jet flow velocity on the radial profile of the mean axial velocity that injected from eight orifices each 5 mm in diameter and arranged along the perimeter of the pipe.…”

Enhancing the flare gas/air mixing process above the flare tip is critical to optimizing flare performance in terms of emissions. A new flare tip design using an aerodynamic nozzle (such as that used in jet engines to increase thrust on takeoff) has been developed to control the flare gas exit velocity and the local mixing above the flare tip. The work described in this paper focuses on understanding the fluid mixing for the new flare tip design. The flow field of a jet injected into a crossflow is found in several systems, including combustion equipment, drying systems, quenching systems, and mixing tanks. A computational fluid dynamics (CFD) technique for simulating radial slot jet flow into crossflow has been validated with experimental results. Sets of experimental data were obtained from an experimental setup, which was designed and built in our laboratory. A hotwire anemometer was used to obtain the measurements of the radial velocity profiles at different axial positions and the centerline velocity profiles that are produced from the impingement of these axial profiles of velocity. A comparison between the simulation velocity profiles and experimental data was performed, and good agreement between the profiles was clearly observed. The obtained data showed that the centerline velocities were increased significantly just after the injection plane of the radial slot due to the reduction of cross-sectional area available for the flow.
