Discussion

Numerical investigation of ice-water interface under turbulent shear flow, highlighting scaling with Stefan number and Péclet number.

Key features of ice morphodynamics scale consistently with the Stefan number and Péclet number across regimes.
Subsurface turbulent shear flow affects ice melting and the morphology of the ice-water interface significantly.
A numerical approach reveals characteristic time scales crucial for predicting global ice melting rates.
Findings enhance predictive accuracy of geophysical melting models by relating morphodynamics to direct numerical simulation datasets.

Perissutti et al. (2025) studied this question.
