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.
