摘　　要：为了研究弯掠叶片对降尘器性能的影响,采用CFD数值模拟的方法,首先研究了不同叶片对叶顶流场和压力面压力分布情况的影响,然后对叶片的前弯角度和前掠角度进行正交试验,用MATLAB对试验结果进行回归分析,并对最优方案进行仿真验证。研究结果表明:前掠和弯掠叶片能够有效改善叶顶流体流动情况;在相同工作条件下,弯掠叶片做功能力最优;通过回归分析得到了降尘器叶片最佳弯掠角度组合为前弯角度5°、前掠角度4°。研究结果可为降尘器弯掠叶片设计提供参考。In order to study the influence of the skewed-swept blade on the performance of dust catcher,the CFD numerical simulation method was used.Firstly,the influence of different blades on the flow field and pressure distribution on the pressure surface was studied.Then,orthogonal experiments were carried out on the forward skewed angle and forward swept angle of the blade,the test results were regressed by MATLAB,and the optimal scheme was verified by simulation.The results show that the forward swept and the skewed-swept blade can effectively improve the tip fluid flow;under the same working conditions,the work ability of the skewed-swept blade was the best;through regression analysis,the best combination of skewed-swept angles was obtained,forward skewed angle is 5°and forward swept angle is 4°.The research results can provide a reference for the design of the skewedswept blade of the dust catcher.
