Study of a Wave-flow Generation Device with ducted bidirec-tional pump impeller
摘要
Abstract
A new type of Wave-flow Generation Device with a ducted bidirectional pump impeller is constructed based on the design principle of the axial-flow pump. In this study, the working principle of the axial-flow pump is analyzed and the back-stepping approach is used to design the device. A comparison with data from theoretical calculations, a numerical simulation, and tank experiments relating to the device shows the power generation effi-ciency of the device in different working conditions. Results show that the device can be started at a flow rate of 0.5 m/s, its output power is close to rated power at a flow rate of 1.8 m/s, and its energy conversion rate is at its highest of up to 23.7% when the working flow rate is below 1.8 m/s. However, when the working flow rate exceeds 1.8 m/s, the energy conversion rate begins to decline because the increase in the tail flow field strongly increases the reversal force to the pump impeller.关键词
