Analysis of Turbine Hydrodynamic Interactions - A Preliminary Investigation
Bibliographic record
Abstract
A tidal current turbine is a device to harness tidal current energy by using a similar mechanical principle as a wind turbine. A group of tidal turbines, distributed in a site, is called a turbine farm. In our previous research, we studied the working principle of a single tidal current turbine and conducted numerical analysis to predict its performance. We identified the importance of studying the hydrodynamic interactions between turbines in a farm to provide an accurate prediction on power output of a turbine. In this paper, we study turbine hydrodynamic interactions by employing a discrete vortex method and the potential flow theory. We analyze the hydrodynamic interactions within a single turbine for different turbine design options, such as blade and arm component. Based on the results from single turbine interactions, we then analyze the hydrodynamic interactions between multiple turbines after specifying turbine distributions in a site. Finally, key factors affecting the turbine power efficiency in the turbine design and farm planning stages, are identified.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
