Simulation of Frictional Melting at the Ski- Snow Interface

This work presents a numerical investigation into the mechanisms of frictional melting at the ski–snow interface, with the aim of understanding the conditions under which localised meltwater films form during gliding. Using a combination of boundary element contact mechanics and an enthalpy-based heat conduction model, the study explores how surface roughness, snow temperature, ski base texture, and sliding speed influence frictional heat dissipation and phase change. Simulation results reveal critical thresholds for meltwater generation, highlighting the strong influence of contact pressure, duration, and material properties. The findings contribute to the broader understanding of snow tribology and have potential applications in ski base design and preparation strategies for optimising glide performance in winter sports.
