Numerical investigation of flow field characteristics of air injected through an inclined radial slot into a crossflowing stream has been studied for gas flaring applications. CFD is used to simulate turbulent mixing between the inclined slot jet and the crossflowing stream. The slot injection angle with respect to the crossflow, the slot jet velocity, and the slot height were varied in this study. Velocity profiles obtained from the simulations were compared to measured profiles. Simulation results showed that the centerline upflow axial velocities increased with decreasing injection angle and increasing slot height. Results also showed that decreasing injection angle increased the horizontal penetration of the jet flow into the crossflow stream.

通过倾斜的径向槽注入交叉流的空气流场特性的数值研究已经在气体燃烧应用中进行了研究。CFD 用于模拟斜槽射流和横流之间的湍流混合。在这项研究中，相对于横流的狭缝喷射角度、狭缝喷射速度和狭缝高度是不同的。从模拟获得的速度剖面与测量剖面进行比较。模拟结果表明，中心线上流轴向速度随着喷射角的减小和槽高度的增加而增加。结果还表明，减小喷射角增加了射流进入横流的水平渗透。
