仿生弯管的冲蚀磨损分析

Erosion Wear Analysis of Bionic Bend

为研究弯管的抗冲蚀磨损性能,仿照扇贝表面建立不同仿生弯管模型,根据流体动力学和冲蚀磨损原理,借助Fluent流体计算软件对不同模型进行仿真模拟。研究表明:在相同边界条件下,正常弯管的冲蚀面积以及速率最大,仿生弯管的冲蚀面积随着仿生肋条的偏心距离增大而减小,冲蚀速率随着仿生肋条的偏心距离增大而增大。

In order to study the erosion resistance of the elbow, different bionic elbow models were established according to the surface of scallops, according to the fluid dynamics and erosion wear principle, the simulation of different models was carried out with the help of Fluent fluid calculation software. The research shows that under the same boundary condition, the erosion area and rate of the normal bend are the maximum, the erosion area of the bionic bend decreases with the increase of the eccentricity distance of the bionic rib, and the erosion rate increases with the increase of the eccentricity distance of the bionic rib.
