| 摘 要： | 利用全隐格式的非稳态压力修正求解方法,分析和研究了对旋叶轮级间流场非定常流动情况,上游尾迹与下游叶片位势作用对流场的影响,并与动态实验结果进行了有益的对比.结果表明:非定常流场的计算更能反映叶轮机实际运行性能,如果能很好地组织对旋叶轮的非定常流动,还可以进一步提高其压比和效率.

| Abstract: | The completely implicit method for unsteady SIMPLE algorithm was utilized to study some problems such as the unsteady flow between two counter rotating rotors, especially the influence on flow field made by the wake flow of upstream and potential affection of downstream. Compared with dynamic experimental results, the numerical simulation for unsteady flow was more fit for the actual characters of turbomachinery and there would be more increases on the pressure rise and efficiency if the structure of unsteady flow in counter rotating fans was organized very well. |
