HYDROMECHANICS ANALYSIS ON LIQUID FLUCTUATION IN MULTI-CHANNEL CONNECTED PIPES
多通道连通管液位振荡的力学分析

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.
