A Model of Ice Friction For an Inclined Incising Slider
Bibliographic record
Abstract
The FAST 2.0 model of ice friction was developed for a vertically oriented speed skate. The model is therefore left-right symmetrical about a vertical plane parallel to the sliding direction. It describes ice friction at sliding velocities sufficiently high to produce a lubricating layer of meltwater, which completely separates the ice and slider surfaces. Friction results from ploughing a groove in the ice and from the shear stress in the lubricating Couette flow. The model takes into account frictional melting, heat conduction into the ice and the lateral squeeze flow of the lubricating liquid. Here we present a new, numerical model, FAST 2.0i, which calculates ice friction for an inclined runner that is incising into the ice. Specifically, we consider an inclined speed skate blade and we use it to predict the variation of ice friction during a typical skating stroke. The model results compare favorably with in situ measurements. Copyright © 2012 by the International Society of Offshore and Polar Engineers (ISOPE).

How this classification was reachedexpand
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.
