折流板除雾器结构尺寸优化数值模拟

Numerical Simulation of Optimized Structure Size of Traverse Baffle Mist Eliminator

运用ANSYS软件对折流板除雾器进行流固耦合数值模拟研究,优化折流板除雾器的结构尺寸参数。选取折流板除雾器约束处最大应力σmax,进口第一块折板的最大应力σmax1和最大挠度wtotal为控制指标,研究了约束孔径、折流板高度及约束边宽度等因素对折流板除雾器力学性能影响规律,结果表明约束孔径20mm、折板高度80mm、约束边宽60mm的条件下折流板力学性能最优,相关计算方法可为折板除雾器的工业设计提供指导。

The ANSYS was used in simulation study of the traverse baffle＇ s fluid-structure interactions （FSI） so that traverse baffle＇ s structure size parameters can be optimized.Taking the maximum stress σmax at the constraint site,the maximum stress σmax1 at the first bend and the maximum deflection wtotal as the control index,the influence of constraint aperture,the baffle＇ s height and the constraint edge width on the mist eliminator＇s mechanical property were investigated.The results show that the 20 mm-constraint aperture,80mm-baffle height and 60 mm-constraint edge width can bring optimal mechanical property to traverse baffle and FSI numerical simulation can provide the guidance to industrial design of mist eliminators.
