Convection in Superposed Liquid and Porous Layers with Heat and Mass Transfer at the Free Surface
Bibliographic record
Abstract
<p>In the present study, the onset of thermal convection in a liquid layer overlying a porous layer in the presence of a free surface with evaporation is investigated. The Navier-Stokes equations are solved for the liquid layer, while the Brinkman model describes the porous layer. Two and three-dimensional geometrical models are considered, with bottom heating and lateral heating. Buoyancy convection, thermocapillary convection and combined convection are studied in detail for different aspect ratios. For the evaporation analysis, two conditions are treated simultaneously at the free surface. In the first, surface tension is assumed to vary linearly with temperature. In the second, a linear saturation temperature is imposed at the free surface to allow evaporation. Different aspect ratios, thickness ratios as well as Marangoni numbers are studied in detail. Results reveal the significant effect evaporation in the liquid layer has on convective flow patterns. </p>

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.
