摘　　要：海流能是海洋能中最易获得、最具灵活性的一种清洁、可再生能源。利用海流能技术发电,有利于改善能源结构,降低化石能源消耗带来的环境污染和气候变化问题,但其来流方向却具有不确定性。本文在大型玻璃水槽中,应用高速摄影机、声学多普勒测速仪(ADV)等先进测试仪器,通过对线性增速管在缓慢来流偏流角分别为0°、10°、20°、30°、40°、50°情形下对转速的影响进行了较系统的试验研究,得出增速管面积比、管长对偏流的纠正范围及其程度。Marine current energy,clean and renewable,is one of the most exploitable and flexible ocean energies.Using the marine current technologies to generate electricity can improve the energy structure and reduce environmental pollution and climate change caused by fossil energy consumption.The uncertainty in the flow direction,however,is a difficult issue.This paper presents an experimental test that was conducted in a large perspex flume using the advanced instruments such as high-speed photography and acoustic doppler velocimetry（ADV） and a comprehensive study of the effect of linear speed-up inlet on the rotational speed of turbine and yawing angle under the oncoming yawing angles of 0°,10°,20°,30°,40° and 50°.Range and extent of the yawing angle rectified by area ratio and length of the speed-up inlet were obtained.
