| 摘 要： | 利用大型流体力学软件FLUENT，对不同结构尺寸和边界条件的蒸汽喷射泵喷嘴内超音速流场进行了3D模拟。探讨了流场内压力和速度的相互作用及其分布规律；讨论了热力学参数和几何参数对流场特性的影响规律；并分析了喷嘴内影响喷射器性能的激波产生的因素。基本上与Dayton和石井博的研究结果一致。 |

| Abstract: | The supersonic flow field in steam ejector nozzle was 3D simulated with the software FLUENT for large computational fluid dynamics. Discusses how the pressure interacts with flow speed and its distribution in the flow field, as well as how the thermodynamic and geometric parameters affect the flow field behavior, with various boundary conditions and structural dimensions taken into consideration. Analyzes the influencing factors on the formation of shock wave which will bring the ejector performance a great loss. Results of the study are in line with the works by Dayton and Ishii. |
| Keywords: | ejector nozzle supersonic flow shock wave simulation flow field |
