摘要
提出一种桨叶设计流速的计算方法,使以此设计的桨叶在一个变化的流速范围内获得较好的捕能效率。首先,对实验地点的海水流速变化进行测试分析,通过计算确定桨叶的设计流速;其次,在叶素动量理论的基础上采用Wilson的优化设计法,通过Matlab软件计算8 kW水平轴潮流能发电装置的桨叶外形参数,并对其在不同流速下性能进行数字预测。最后,在实际海况下对捕能装置进行测试,实验结果表明捕能装置性能和数字预测基本一致,验证了设计方法的正确性和有效性。
A method to calculate the optimum flow velocity range which made the blade have better capture efficiencywas proposed. First of all,the water velocity variation of the experimental site was tested and analyzed; the designed flowvelocity was determined by the calculation. Secondly,the blade momentum theory and Wilson's optimization designmethod were combined,the blade shape parameters of 8 k W horizontal axis marine current turbine were calculated byusing Matlab software,and the performance under the different flow velocity was forecasted by digital computation.Finally,the performance of the device under actual sea condition was tested. The experimental results show that actualperformance of the device is almost same with the digital prediction. The correctness and effectiveness of the method areverified.
