摘要

本研究比较了收缩和膨胀几何形状下二维和三维 CFD 模型输出的侵蚀模式和侵蚀程度。使用 ANSYS Fluent 软件模拟了一个收缩的圆形截面几何体,并将模拟结果与已公布的实验数据进行了比较。模拟结果表明,二维和三维 CFD 模型与实验数据在流体流动特性(如速度剖面和大小)方面有很好的一致性。模拟结果还表明,二维和三维 CFD 模型对侵蚀模式和侵蚀程度的描述是等效的。与二维 CFD 模拟相比,三维 CFD 模拟能够提供更多信息,尤其是在整个几何形状的侵蚀分布方面。

A Numerical Comparison of 2D and 3D CFD Modelling for Contraction and Expansion Geometries with an Emphasis on Solid Particles Erosion
In this study, erosion patterns and magnitude are compared between the outputs of 2D and 3D CFD models in contraction and expansion geometries. ANSYS Fluent software was used to model a circular cross-section geometry with a contraction and the results were compared to published experimental data. The simulation findings showed that there is good agreement between the 2D and 3D CFD models and the experimental data in terms of fluid flow properties such as velocity profiles and magnitude. It also demonstrated that the 2D and 3D CFD models' representations of erosion patterns and magnitudes are equivalent. The 3D CFD simulations were able to provide more information than the 2D CFD simulations, particularly in terms of erosion distribution over the entire geometry.
