Geometry generation for DHV tidal turbine – Basic Python code and implementation in ANSYS-CFX and Rhinoceros

The flow speed which acts on tidal turbines can be increased based on a wide range of approaches. A unique feature of the Davidson Hill Venturi (DHV) turbine is the Venturi shaped structure is produced from individual hydrofoils. This concept includes further parameters, which can be in- dividually changed to find an overall optimum solution. As part of the research project, a general geometry description is provided, which describes the form of the structure by utilising two sym- metrical bell curves. A Phyton script allows the generation of this geometry based on simple inputs. Furthermore, the exemplary integration of this in ANSYS-CFX via SpaceClaim is provided in this dataset. This includes the script file, an example Workbench and a video showing the build-up. An additional Grasshopper code allows to integrate the geometry generation in the CAD software Rhinoceros to allow more complex geometries. The presented data can help to improve the gener- alisation of future optimisation work on this tidal turbine.可通过多种途径提升作用于潮汐涡轮机的来流流速。戴维森山文丘里（Davidson Hill Venturi, DHV）涡轮机的独特特性在于，其文丘里造型的结构由多个独立水翼构成。该设计概念包含多项可独立调整的参数，以便寻求全局最优解。作为本研究项目的组成部分，本数据集提供了一套通用几何描述方法，该方法通过两条对称钟形曲线来刻画该结构的外形。附带的Python脚本可通过简单输入参数生成该结构的几何模型。此外，本数据集还提供了通过SpaceClaim将该几何模型集成至ANSYS-CFX的示例流程，包含脚本文件、一个Workbench示例工程以及一段展示搭建过程的视频。额外附带的Grasshopper代码可将几何生成流程集成至CAD软件犀牛（Rhinoceros）中，以支持更复杂的几何建模。本数据集所提供的内容，可助力提升该潮汐涡轮机后续优化工作的通用性。
