小型推板式波浪水槽的性能测试分析
|
摘要
波浪水槽是研究波浪运动及其与结构物相互作用问题的试验设备,其造波的重复性、稳定性和沿程衰减程度会影响试验方案设计和所采用的试验结果分析方法.文中结合武汉理工大学交通学院流体力学试验室新改建的小型推板式波浪水槽,展开了水槽造波性能测试分析,主要涉及规则波的波高和周期的重复性、稳定性,以及波高沿程衰减程度.结果表明,水槽造波的波高和波周期的重复性与稳定性误差,以及单位距离波高沿程衰减程度均较小.
A wave flume is an important experiment facility to study the problem of wave motion and wave-structure interaction.The important factors,such as the repeatability,stability and the attenuation degree of the wave have remarkable effect on the experiment design and the choice of result analysis method.The small piston-type wavemaker flume at the Fluid Mechanics Laboratory,School of Transportation,Wuhan University of Technology,was used to conduct the performance test and analysis of flume wave,including the repeatability and stability analysis on height and period of regular wave and the attenuation degree analysis on wave height.The results indicate that the errors on wave height,repeatability and stability of period,and the attenuation degree of wave height in unit distance are small with wave flume.
