Numerical Investigation On Water Extraction From The Atmosphere By Underground Condensation Water Production System
Bibliographic record
Abstract
Abstract Underground condensation water production system is a low capacity water harvesting method that is suitable for hot and humid climate regions. In this method, the hot and humid airflow is directed to the buried pipes in the ground and, the air is gradually cooled down and the vapor contained therein appears as droplets of water on the pipe surface. The assessment of the amount of water extraction in the condensation system of hot and humid air is the main objective of this investigation. A computational code using MATLAB software is developed to evaluate the amount of water production from humid air in the buried pipes into the ground at a depth of 0.5 m with various lengths and obtain the optimal length of the pipe. Numerical results indicate that water production by considering the initial conditions in this study is about 1 kg per day. The influence of important and effective parameters in underground condensation water production system such as pipes material, air temperature, air humidity, soil temperature, input speed have been investigated. Also, the influence of effective parameters on the performance of the condensation system, including temperature and humidity of inlet air, soil temperature and inlet air velocity, have been evaluated.

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.
