摘要: |
在喷管喉部后方注水,使喷喉临界状态在一定范围内不随出口环境的压力而变化,并对其流动特性进行了分析。在一维定常流动假设的基础上,采用控制容积法建模,在一定参数范围内选代计算喷管背压、喷水量与喷管几何参数之间的数值关系,并对计算结果进行分析和讨论。 |

Abstract: |
The general features of flow in converging-diverging nozzle with water addition areinvestigated. water is injected at down stream of the throat in order to keep throat critical when theback pressure is changed. With control-volume methane a model is developed under the assumption ofsteady one-dimensionnal and numerical solution is obtained. |
