| 摘 要： | 利用原始变量,交叉网格的方法,以及采用κ-ε湍流模型,计算了离轴受限射流三维湍流流场,计算结果与用LDV测量结果作了比较,结果是满意的。计算结果提供了这样一个复杂的三维流场的清晰图象,为研究具有离轴射流的预燃室的稳燃机理提供了很多有用的信息,对计算结果作了详细的分析和讨论后,指出这样一个流场的重要三维特征是在θ方向梳线有大角度的扭曲。

| Abstract: | Using primary variables and staggered, the 3-D turbulent flow field for an off-axis confined jet was computated by k-ε model of turbulent flow. Computing results on comparison with measurements are satisfactory. The computing results have provided much information on the flow pattern and given a basic understanding of the mechanism of stable combustion for pre-cornbustion chambers with an off-axis confined jet. A detail analysis shows that one of the major characteristics of the flow field is the large twis... |
