摘　　要：采用数值模拟与缩比试验相结合的方法,对环形弓射器内部流场进行了分析,对数值模拟结果与缩比试验结果进行了比对,验证了数值仿真模型及选取的控制方程的有效性和准确性。结果表明,采用数值模拟得到的结果与缩比试验结果基本一致,数值模拟能够正确反映环形引射器流场状况。Numerical simulation and sub-scale test was applied to analyse flow field of annular ejector. The results of the numerical simulation and sub-scale test are compared, which prove that the numerical simulation model and the selected control equation are effective and correct. The results show that the results of numerical simulation and sub-scale test are basically same, and flow field of the annular ejector can be reflected accurately by numerical simulation.
