中文摘要：

基于控制容积法和协调一致的求解压力耦合方程的半隐方法（SIMPLEC），应用Realizablek-ε紊流模型，对单圆孔、双圆孔和四个圆孔的横向紊动射流流场进行了数值模拟，分别得到了射流与主气流速度比尺为4和6的速度场。结果表明：射流比尺越大，射流越不容易发生弯曲；在多孔射流中，水平方向速度“变化明显且幅度较大，并出现了多个极值点；射流孔后存在尾迹区，第一个射流孔后，“孔吸现象”更加明显；由于前一个射流的遮挡作用，后面的射流更不容易发生弯曲。

英文摘要：

Numerical simulation was performed to investigate the flow characteristics of the lacunaris turbulent jet-to-crossflow, based on a control-volume numerical procedure utilizing the semi-implicit method for pressure-linked equations-consistent （SIMPLEC） pressure-velocity coupling arithmetic, using the realizable k-εmodel for the single round hole, double round hole, and four round hole. We got the velocity fields at the ratio of 4 and 6. The flow mechanism of lacunaris turbulent jet-to-erossflow was analyzed systematically at the different ratio of jet-to-crossflow.
