多孔平面射流混合区流动的数值计算

CALCULATION OF FLOW IN MIXING REGION OF JET FROM A SERIES OF HOLES

用K-ε湍流模型和混合有限分析法,模拟均匀排列无限多孔平面射流混合区内的流动。计算了不同相对孔间间距对混合区内流动特性的影响,得到了一些重要的关系。所得结果较为理想,对研究均匀排列多孔射流的流动有一定的价值。

In this paper, the K-e turbulence model and Hybrid finite Analytic Method are used to simulate the flow in mixing region of plance jet from a series of holes. The effects of relative nozzle-distance on the behavior of the flow are calculated. The important relations of flow development are obtained.
