摘要：

This paper firstly compares different types of energy recovery devices and their technological details. The studies in this paper are emphasized on the positive displacement approach which has higher energy transfer efficiency. And then a rotary hydraulic energy recovery unit with data acquisition system is set up. Experimental results are obtained on the fluctuations of pressure and flux to and from energy recovery unit. Energy transmission efficiency are also evaluated. Secondly, dynamic studies on rotor starting-up and stable running stage have been done. CFD method is used to optimize flow channel through which rotor get maximum angular momentum from fluid to start running. Although experimental background is associated with reverse osmosis desalination process the principles and theories presented in this paper are applicable to all devices that based on the positive displacement and circumstances in which pressure difference between two fluids exists.
