Study of a Vertical Axis Wind Turbine for Low Speed Regions in Saudi Arabia
Bibliographic record
Abstract
There are number of sources for generation of power but in the recent years wind energy shown its potential as the clean source of energy and contributing to the high-energy demands of the world.Vertical axis wind turbine (VAWT) is the best option for the area, which are under load sheading.Thus, in this paper, VAWT blades for low average wind speed regions like Al Khobar in Saudi arabia is designed and implemented.Performance and power produced are investigated and utilized in the design and the economic analysis.An experimental and theoretical review on the performance of Savonius VAWT is presented.The turbine was made of Aluminium alloy with a blade angle of 160 degree and maximum coefficient of power, Cp, of 0.286.The results of this current study showed that the power output, with speed of minimum speed of 12-15 m/s generate 40-80 watts with an efficiency of 31~35%.

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.
