Abstract
In this study, parametric sensitivity analysis using dimesionless sensitivity analysis and temperature polarization was used to investigate the sensitivity of the mass flux to the different parameters associated with the air gap membrane distillation (AGMD) process for pure water production. The model of AGMD used in this study is the approximate model proposed by Jonsson et al., which neglects the temperature polarization effect. The effect of temperature polarization is studied using another model developed by Banat and Simandl. The results obtained show that the mass flux of pure water production is highly sensitive to the feed bulk temperature, membrane porisity at low porosity values, and air gap width. Results also show that increasing the membrane thickness decreases the mass flux of pure water and decreases the temperature polarization effect. In addition, results show that the temperature polarization effect becomes significant as feed bulk temperature increases. Increasing the film heat‐transfer coefficients, increasing the diffusion path, or decreasing the membrane porosity can reduce the temperature polarization effect significantly.

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 it
