Through the numerical simulation,the internal flow fields of jet pump are calculated under the condition of different throat lengths and the optimal sizes of throat are obtained.
通过数值仿真,分别计算了具有不同喉管长度的喷射泵内部流场,并经过分析确定了喷射泵的最优喉管尺寸,计算数据和试验数据对比非常接近,证明了数值仿真结果是合理的、可信的。
This paper presents ample experimental data which show that the improvement ofwater-jet pumps from short throats into long ones costs a little work and expense and the im-proved throat is efficient and energy-saving.
本文从理论方面阐述和用实验数据证实,长喉管射水抽气器效率高,能耗低,并指出改进短喉管射水抽气器工作量不很大,花费不多,见效快,效益显著。
No packer is installed at the bottom end of the jet pump within which a group of nozzles and throat diffusers are installed.
该冲砂泵利用水力喷射泵没有运动件这一优点,依靠动力液与地层液的能量转换进行工作,动力液与混砂液沿着油管中心孔返出地面,喷射泵底端不安装封隔器,喷射泵内部装有1组喷嘴和喉管扩散器,同时实现进口、出口和吸入口有效结合,并配套双级管柱等其他工艺来实现低压漏失井的冲砂作业。
Relationship between optimal length of throat pipe and area ratio was analyzed.
应用气液两相流动的双流体模型,数值模拟了射流器内臭氧—水的混合过程,得到了喉管内流场的参数分布,揭示了利用射流器进行臭氧—水混合的工作机理,为射流器结构参数优化设计和性能预测提供了有效手段。
