The present research depicts an analysis of the implementation of computational fluid dynamics (CFD) in the study of pumps such as turbines and PATs. To highlight the benefits of CFDs for PAT studies, results from both experimental tests have been compared to better understand the reproduction error phenomena. For this, data analysis used in successful models has been applied to determine variables and parameters, and to report a low relative error. The results show that most of the studies focused on fixed speed rotation with some cases of variable speed rotation. Furthermore, there is not enough information in the academic literature for PAT of axial and mixed flows with fixed and variable speed. Finally, turbulence models based on Reynolds average Navier–Stokes (RANS) have been used to simulate PATs with fixed speed rotation in most cases.

CFD数值研究在泵作为涡轮机工作时的适用性分析

本研究描述了计算流体动力学 (CFD) 在涡轮机和 PAT 等泵研究中的实施分析。为了突出 CFD 对 PAT 研究的好处，比较了两个实验测试的结果，以更好地了解复制错误现象。为此，已应用成功模型中使用的数据分析来确定变量和参数，并报告较低的相对误差。结果表明，大多数研究集中在定速旋转和变速旋转的一些情况下。此外，学术文献中没有足够的关于定速和变速轴流和混合流 PAT 的信息。最后，在大多数情况下，基于雷诺平均纳维-斯托克斯 (RANS) 的湍流模型已用于模拟具有固定速度旋转的 PAT。
