摘要

对随钻测井系统中井下涡轮发电机的关键部件进行了研究。首先

建立了一种水力性能较高的涡轮模型;然后

基于计算流体力学(CFD)理论

采用Fluent软件对不同叶片参数的涡轮模型进行了紊流流场研究

并分析了流量、转速对涡轮流场的影响;最后

通过涡轮发电机地面单向水利实验验证了流量、转速、负载与涡轮发电机输出电压的关系。仿真结果表明:15叶片、叶片进口角30以上、出口角45以下、中弧线圆弧半径40 mm以内对应的涡轮模型水力性能较好

但水力效率过高也会降低涡轮的工作寿命

因此

在一定范围内增大流量、转速对提高涡轮水力效率具有积极影响。所建立的涡轮模型能够提高涡轮的输出功率并保证其工作寿命。

Abstract

The work performance of key components in an underground drilling turbine generator for the Logging While Drilling(LWD) were researched. First

a kind of high performance hydraulic turbine model was established. Then

the turbine model with different blade parameters were studied in the turbulent flow field based on the Computational Fluid Dynamics(CFD ) theory by using the Fluent software. The effects of flow rates

rotational speeds on the turbine flow field were analyzed. Finally

the relationship of flow rates

rotational speeds

loads and turbine generator output voltage were verified through a ground one-way water conservancy experiment for the turbine generator. The simulation analysis results show that the turbine model with 15 blades

import blade angle above 30?

export angle below 45?

the arc radius of 40 mm or less has excellent hydraulic performance

however

the higher hydraulic efficiency will reduce the working life of the turbine. It suggests that improving the efficiency of hydraulic turbines by increasing the flow and speed should be controlled in a certain range. The established turbine model improves the output power of the turbine and ensures its working life.
