Data underlying the research of Positive Displacement Reversible Pump Turbine - TU Braunschweig design

Inside EU Horizon 2020 project: ALPHEUS, a Positive Displacement Reversible Pump-Turbine is studied as potential use for low-head pumped hydro storage applications. Design calculations and 2.5D CFD simulations of a reversible lobe pump-turbine assess expected characteristic curves for a model scale rig in Technische Universität Braunschweig. <br>A PhD thesis that describes the CFD setup and all the relevant numerical results is included : see Chapter 6. An Excel file gathers results from CFD simulation (flow rate, power, efficiencies, torques, pulsation level).The TwinMesh software is needed to generate the deformable mesh for each rotation position. The stator mesh file (created in ANSYS) is included as reference for TwinMesh, then TwinMesh exports and prepares all the setup to ANSYS CFX. The CFD boundary conditions to be indicated for each operating condition are described in the PhD thesis, Chapter 6.Two CFX files (exported from TwinMesh) are indicated as reference for pump and turbine mode. They cannot be run without the mesh files generated from TwinMesh and having a valid TwinMesh license. All relevant CFD results were saved to .csv files.

本数据集源自欧盟地平线2020（EU Horizon 2020）计划ALPHEUS项目，研究将容积式可逆水泵水轮机（Positive Displacement Reversible Pump-Turbine）应用于低水头抽水蓄能场景的可行性。针对布伦瑞克工业大学（Technische Universität Braunschweig）的模型级试验台，通过对叶瓣式可逆水泵水轮机开展设计计算与二维半计算流体动力学（2.5D CFD）仿真，评估其预期特性曲线。
本数据集收录一篇阐述CFD设置与全部相关数值结果的博士学位论文，具体内容参见第6章；另有一份Excel文件汇总了CFD仿真的相关结果，涵盖流量、功率、效率、转矩及脉动水平。
需使用TwinMesh软件为每个旋转位置生成可变形网格。本数据集还收录了由ANSYS创建的定子网格文件，作为TwinMesh的参考文件；随后TwinMesh会导出所有配置并将其导入ANSYS CFX中。各运行工况所需的CFD边界条件已在该博士学位论文第6章中详细说明。
另有两份从TwinMesh导出的CFX文件，分别作为水泵工况与水轮机工况的参考文件。若无TwinMesh生成的网格文件及有效TwinMesh许可证，则无法运行这些文件。所有相关CFD结果均已保存为.csv格式文件。
