Bubble coalescence inhibition in volatile solutions at elevated temperatures
Bibliographic record
Abstract
An experimental study on the effect of liquid temperature on coalescence of bubble pairs in volatile solutions is presented. Alcohols with low molecular mass were used as volatile additives, and the temperature investigated ranged from 25–60 °C. At low temperatures, earlier results showing increases in coalescence percentage with increasing temperature were reproduced. However, by increasing the temperature to a certain value, the coalescence percentage decreased, which is caused by the Marangoni effect induced by solute evaporation from the liquid bulk to the gas bubble. To the best of our knowledge, this phenomenon has not been previously observed. A theoretical model was derived to include the mass transfer induced Marangoni effect in the film drainage process, and the close agreement between theoretical and experimental results confirmed our suppositions. Results may be applied to various fields, especially in direct‐contact evaporators, and support developments in film drainage theory to account for interfacial mass transfer in distillation columns and boiling systems.

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.
