IN-SITU TESTING OF A DARRIEUS HYDRO KINETIC TURBINE IN COLD CLIMATES
Bibliographic record
Abstract
There is a significant potential for kinetic turbine technology in Canada. An estimated 225 GW of power have been identified in wave and tidal energy with river energy yet to be adequately assessed. Manitoba is an ideal location for river turbines, and thus this study was conducted to demonstrate the turbine’s feasibility in cold climates. Frazil ice is a cause for concern in northern regions because it reduces the output power of larger hydro installations and can adversely impact kinetic turbine installations. Along with environmental concerns, a 5 kWe Darrieus turbine was evaluated for its performance. Sources of power loss were quantified in this study. It was found that the turbine’s support arms contributed a significant loss of up to 66%. The non-ducted Darrieus design self-started in a flow of 2 m/s and saw a peak power coefficient of 0.35 while producing reliable and consistent power to the grid throughout the winter and summer months. ii

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
