摘要
本文应用一种“换算法”,计算了二元喷管射流流场,此法将轴对称射流的流动特性通过换算系数进行换算,即可得到非轴对称射流的流动特性。应用此法得到的数值结果与实验数据吻合较好,本文还对二元喷管射流温度场与轴对称喷管射流温度场进行了比较,取得了一些重要的结论。
This paper calculates the properties of 2-D nozzle jet by applying the 'scaling method'. That is, the properties of the nonaxisyinmetric jet can be obtained from the properties of an axisymmetric jet, after scaling by an appropriate scaling factor. The numerical results obtained by this method are in good agreement with the experimental data. The compark on of the total temperature distributions between axisymmetric nozzle jet and 2-D nozzle et is made in this paper, the some important conclusions are gained.
