Abstract
Fluid slosh in partly-filled tanks is modelled as a two-phase flow, and solved using a Navier-Stokes (NS) solver, while the interface of two fluids is tracked using the VOF technique. The fluid slosh in cleanbore and baffled scale model tanks was further characterised in the laboratory, under different fill levels and excitations. The validity of the slosh model, reduced to the scale model tank, was evaluated using the measured data in terms of fundamental slosh frequency, and transient and steady-state slosh forces and moments over a wide range of conditions such as the tank configuration, fill level and acceleration excitation. The model results showed reasonably good agreements with the measured data, irrespective of tank configuration, fill level and the acceleration excitation. It is concluded that the dynamic fluid slosh model can effectively predict the forces and moments associated with 3-D fluid slosh observed under lateral or longitudinal excitations. The fluid slosh model may thus be integrated to the vehicle model to investigate partly-filled tank vehicle responses and the role of baffles. The slosh forces and moments responses of a full-size tank model were subsequently evaluated using FLUENT software.

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 it
