摘　　要：采用CFD软件FLUENT对燃料筒中液位传感器做上升运动时液面的变化情况进行数值模拟,发现附着于传感器表面的液体的高度在某一范围上下波动。当传感器上升速度降低时,液体的附着高度也降低;当传感器上升速度不变时,进液速度的增大令液体水平面上升,因而附着高度也减小。传感器刚开始运动时,附近液面的波动比较大,然后波动减小并保持在小范围内。计算结果可为液位传感器的动态校准提供数值依据和参考。The changes of liquid level when the liquid level sensor moving upward in fuel canister is simulated by using CFD software FLUENT. The result shows that the ＇height of liquid attaches to the surface of sensor moving up and down in a certain range. When ascending velocity of sensor reduces, the height of liquid attached to sensor also reduces. When ascending velocity of sensor keeps constant and feed speed increases, the water level of liquid rises and the attachment height reduces. When the sensor just starts movement, liquid level nearby fluctuates great, and then the fluctuations decrease and remain within a small range. The calculation results can provide numerical basis and reference for the dynamic calibration of liquid level sensor.
