摘要
从流体力学相关理论出发,建立了3通道连通管液体运动的力学模型,推导了液位振荡的运动方程,进一步扩展到多通道连通管.运用Matlab仿真平台,在不同系统参数变化的情况下,对振荡规律进行了分析.最后,通过3通道连通管系统实验证明:连通管液位振荡模型及理论分析正确,能够描述连通管内液体的振荡规律,为进一步消除液位振荡打下理论基础.
Measurements of liquid level are affected by liquid fluctuation in connected pipe. To address this problem, mathematical model of liquid flows based on a three-channel connected pipe is set up with the knowledge of hydromechanics. Mathematic equations of liquid fluctuation in the three-channel connected pipe are obtained and generated to the case of multi-channel connected pipe. With Matlab software, properties of liquid fluctuation in time domain are obtained for different system parameters. Experimental results show that our analysis about the multi-channel connected pipe is correct.
