Data underlying the research of Positive Displacement Reversible Pump-Turbine - CFD Validation

Inside EU Horizon 2020 project: ALPHEUS, a Positive Displacement Reversible Pump-Turbine is studied as potential use for low-head pumped hydro storage applications. This dataset includes the CFD setup of a lobe pump-turbine that was used to validate the numerical mode with the experimental data produced in the ALPHEUS project, and published in Deliverable D2.5 in https://data.4tu.nl/datasets/370f4182-827c-4e45-9781-94c61cfd6509 .<br>PhD thesis that contains all the relevant analyses and comparisons between CFD and Experiment results is included: see Chapter 4. ANSYS CFX and TwinMesh were used as solver and mesh creation. The TwinMesh software is needed to generate and export the deformable mesh to CFX, which size is too big to be included in this dataset, but the reference CAD is included, as well as the CFD boundary conditions which are described in the PhD thesis. Main results showed average flow rate values, pressure and u- and v- velocities fields. Velocity fields are added in this dataset (.csv) and they were exported to MatLab.

本数据集隶属于欧盟地平线2020（EU Horizon 2020）计划下的ALPHEUS项目，研究目标为一款适配低水头抽水蓄能应用的容积式可逆水泵水轮机。本数据集包含一款罗茨泵水轮机的计算流体动力学（Computational Fluid Dynamics, CFD）仿真设置，该设置依托ALPHEUS项目产生的实验数据对数值模型进行验证，相关成果已发表于项目交付件D2.5，详情见链接https://data.4tu.nl/datasets/370f4182-827c-4e45-9781-94c61cfd6509。
本数据集还收录了涵盖全部CFD与实验结果相关分析及对比内容的博士学位论文，具体参见其第4章。本研究采用ANSYS CFX作为求解器，TwinMesh作为网格生成工具。
需借助TwinMesh软件生成并导出可变形网格至CFX，但该网格文件体积过大，无法纳入本数据集。不过数据集已提供参考计算机辅助设计（Computer Aided Design, CAD）模型，以及博士论文中详述的CFD边界条件。
本数据集的核心结果包含平均流量值、压力场以及u、v方向速度场。其中速度场以逗号分隔值（Comma-Separated Values, CSV）格式存储于本数据集，且已导出至MatLab环境。
