🔬研究者:Provides a validated erosion model and optimization framework for hydrokinetic turbine design, useful for further research in renewable energy and fluid dynamics.

🏢実務担当者:Offers a design tool for micro-hydrokinetic turbines in sediment-laden rivers, aiding project developers in tropical regions.

🏛政策担当者:Highlights the potential of micro-hydrokinetic energy in tropical rivers, informing policies for decentralized renewable energy.

Code and data underlying a study of blade shape selection for micro-hydrokinetic rotors working in rivers that carry suspended sediment. Contents: A MATLAB implementation of a steady blade element momentum solver, formulated so that the inflow-angle residual has a guaranteed bracketed root and the returned solution does not depend on solver settings. An erosion routine of the Oka family in which the angle at which a grain meets the surface is obtained from a Stokes-number partition of the arriving flux, instead of being equated with the local incidence; the nose contribution is evaluated in closed form and introduces no fitted constant. An NSGA-II driver that trades predicted wear against energy capture under geometric, manufacturability and rotor-availability constraints. Analysis scripts covering global sensitivity, robust-objective evaluation, the availability study and resampling of the flow record. Data: A flow-speed series measured in the River Wiwi at the KNUST campus, Kumasi, Ghana; section aerodynamic polars; digitised measurements from three published rotor experiments and from one published set of impact-angle erosion tests, both used for validation; and the result sets reported in the accompanying article. Requirements: MATLAB R2023a or later with the Global Optimization Toolbox. The Parallel Computing Toolbox is optional. The package is self-contained and clears its 92-case regression suite from a clean MATLAB path. Documentation: README.md carries a directory map and instructions for running the code; DATASETS.md records what each dataset feeds and which published result it reproduces. Access: This deposit is catalogued openly and its descriptive metadata may be read by anyone. The deposited files themselves sit behind controlled access and can be obtained by requesting them through Zenodo, with the corresponding author's approval.
