Friction-induced heating, melting, and refreezing of a snow grain in contact with a cross-country ski

Contents: apparent_pressure/ – Apparent pressure distributions p_ap(x) along the ski (front and rear loading zones, e.g. S05L01, S05L08), used as input for the contact model, with accompanying plots. asperity_pressure/ – Time/position-resolved asperity pressure series p_asp(x) for rough (cp_r_*) and smooth (cp_s_*) grinds at normal loads of 350 N and 700 N, split into front (_f) and rear (_r) contact zones, with summary plots (_fr.png). runsurf/ – Triangulated 3D surface scans (STL) of the rough and smooth cross-country ski base grinds, obtained by optical 3D microscopy, used to derive asperity distributions (Table 1 of the paper). heat_r_F700_v08_T01_mod.m and .mph – COMSOL model file and exported MATLAB LiveLink script for the representative simulation case (rough grind, 700 N, 8 m/s, initial temperature −1 °C), implementing the boundary heat source, phase-change (apparent heat-capacity) formulation, and mesh/solver settings described in Section 2.3 of the paper.
