摘要 采用数值模拟方法进行了FB-4000-1000钝后缘风机翼型的气动特性分析及底阻减阻研究。研究了三种后缘隔板布局对风机翼型气动特性的影响;其中一种隔板布局以升力损失为代价实现线性段减阻约40%,迎角区间平均减阻约25%;另一种布局在几乎没有升力损失的情况下,实现平均减阻约10%。 Computational simulations were introduced to analyze FB-4000-1000 airfoil and its drag reduction with trailing-edge splitters.Three kinds of splitters were study.One of them gave 40% drag reduction in the linear lift regime,and 25% reduction of the average lift between and attack angles at the cost of lift decrease;Whereas another of them gave 10% reduction of that average drag with little lift decrease.
