Measurement of the Liquid−Deposit Interface Temperature during Solids Deposition from Wax−Solvent Mixtures under Sheared Cooling
Bibliographic record
Abstract
The liquid-deposit interface temperature for solids deposition was measured under sheared as well as static cooling from prepared mixtures of two petroleum waxes and a multicomponent paraffinic solvent (C 9 −C 16 ) at different coolant temperatures. The interface temperature and location were obtained from the rate of change of temperature at fixed radial locations in a cylindrical vessel, while maintaining the coolant temperature below the wax appearance temperature (WAT) of the wax−solvent mixture. In addition, precipitation-filtration experiments were performed on several wax−solvent mixtures at a temperature below the respective WAT, which confirmed that the WAT of the filtrate was 1−2 °C less than the precipitation and filtration temperature. For all sheared- and static-cooling experiments, with both wax samples, the interface temperature throughout the deposit-growth process was found to be equal to the WAT of the liquid phase. The results of this study validate the constant-interface-temperature assumption made in the heat-transfer approach for modeling solids deposition from waxy mixtures but do not support the increasing-interface-temperature assumption in the molecular-diffusion approach.

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.
