摘要

摘要: 对表面光滑和有脊状结构的大尺度回转体模型在风洞中进行了变速度、变攻角试验,为脊状表面减阻技术的工程化应用提供了参考.对比分析发现:来流速度对脊状表面减阻效果有很大影响,减阻效果随速度增加呈现先增大后减小的趋势,在某一速度达到最佳,减阻效果提高20%;攻角对脊状表面减阻效果影响有限;脊状结构的存在对模型升力系数和俯仰力矩系数几乎没有影响.

Abstract: Experiments of large-scale cylinder model with smooth and riblet surfaces were carried out under different speeds and attack angles in wind tunnel,providing a reference for engineering application of drag reduction technique about riblet surface.Results from comparison and analysis are as follows:wind speed has a great influence on drag reduction effect of riblet surface.Drag reduction effect increases first,then decreases with increasing wind speed,and reaches to peak at certain speed.The drag reduction effect could exceed 20 percents.Attack angle has limited influences on drag reduction effect of riblet surface.The riblet structure has almost no influence on the lift coefficient and pitching coefficient of model.
