A Two-zone thermal model for predicting the effects of heat transfer on the variation of ice crystal size distribution in slurries
Bibliographic record
Abstract
A two-zone thermal model has been developed to predict the effects of heat transfer on the size distribution of ice crystals in ice slurries under stagnant conditions. The model extends the homogeneous model recently developed by taking into account the stratification of ice crystals due to gravity. Under adiabatic conditions, the crystal sizes slowly grow due to Oswald ripening, but when heat is externally applied and the ice crystals melt and diminish in size, smaller crystals tend to float to the top of the cell and separated zones of clear liquid and an ice slurry mixture emerge. The temperatures in the two zones diverge as the temperature of the liquid zone rises while that of the ice slurry zone remains constant due to phase change. Measurements of ice crystal size distributions were obtained using direct video observation of the ice slurry crystal behaviour in a stagnant flow cell. For the heating cases, the time to melt all the crystals was sufficiently short (

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.
