| 摘 要： | 采用FLUENT软件对应用于斯特林发动机小空间燃烧室的不同类型的引射器的引射特性进行了计算研究.研究结果表明:在一次流体总质量流量和喷嘴总流通面积相同的条件下,多孔式喷嘴引射器的速度、温度及浓度分布均匀性明显优于中心、环形式喷嘴引射器,喷孔数量越多均匀性越好；多孔式喷嘴引射器的引射系数明显大于中心、环形式喷嘴引射器,喷孔数量越多引射系数越大.

| Abstract: | The entrainment performance of four types of ejectors used on Stirling engine was investigated by simulative calculation software FLUENT. The results indicated that the distribution uniformity of velocity, temperature and density of multi-hole nozzle ejector was superior to central and circle nozzle ejector with the same primary mass flow and nozzles area and the uniformity increased with the number of nozzle holes. The entrainment performance of multi-hole nozzle ejector was superior to central and circle nozzle ejector and also increased with the number of nozzle holes. |
