This dataset provides supplementary materials for Wei, Z., Kristiansen, T., Kristiansen, D., &amp; Shao, Y. (2026). Experimental and theoretical investigation of drag loads on side-by-side flexible blades in a uniform current. Journal of Fluids and Structures, 143, 104546.DataThe file `CWT_test_cases.csv` contains a list of all test cases, detailing the blade properties (including dimensions and the number of blades per bunch) and current speed. The associated non-dimensional parameters are also provided.The folder `experimental_data` contains the processed experimental data.The dataset is published under the CC BY 4.0 license – © Copyright 2024 Technical University of Denmark.CodeThe Python script `analytical_drag_reduction.py` solves the non-dimensional static governing equation of motion for a flexible blade subjected to a uniform current, yielding the reconfiguration number.The Python script `linear_stability.py` solves the non-dimensional small-amplitude flutter equation for an umdamped cantilever beam in axial flow with no friction or gravity.The scripts are published under the MIT license – © Copyright 2024 Technical University of Denmark.VideosThe folder `numerical_simulation_videos` contains some simulation videos generated using the numerical model (Wei2024). Each video is labeled according to four key parameters: the Cauchy number Ca, the buoyancy parameter B, the aspect ratio l/b, and the number of blades per bunch N.The folder `experiment_videos` contains some videos recorded during the experiments. Each video is annotated with the number of blades per bunch N, the aspect ratio l/b, the blade thickness d, the submergence of the struts d1, the buoyancy parameter B, the current speed U, and the Cauchy number Ca.The videos are published under the CC BY 4.0 license – © Copyright 2024 Technical University of Denmark.PhotoThe photo `test_section_photo.png` was taken in the lab during one experiment.The photo is published under the CC BY 4.0 license – © Copyright 2024 Technical University of Denmark.<br>
