微管可控充气技术研究

Controllable Filling Technology Relied on Micron Fill-tube

摘要: 本文采用基于燃料室和靶室独立控温的温度梯度法实现了燃料可控注入，验证了通过内径5 μm充气微管注入燃料的充气技术路线可行性，并研究了初始充气压力、靶室温度和燃料室温度对充气过程的影响。结果表明，初始充气压力为86 kPa、靶室温度恒温至19.5 K时，控制燃料室温度即可控制燃料注入量。

Abstract: The temperature gradient was employed to inject the fuel under control based on the fuel reservoir and the target chamber temperature controlling respectively, and the filling technology feasibility was verified by using a 5 μm diameter fill-tube. Additionally, influences of initial filling pressure, target chamber and fuel reservoir temperature on the filling processes were discussed. The experiment results indicate that the injection rate can be controlled by adjusting the fuel reservoir temperature when the initial filling pressure is 86 kPa and the target temperature is 19.5 K.
