WebThe term "Coulombic viscosity" is introduced here to define an empirically observed phenomenon from experiments conducted in both microgravity, and in ground-based 1-g conditions. In the latter case, a sand attrition device was employed to test the longevity of aeolian materials by creating two intersecting grain-circulation paths or cells that would … Webtension σ = 72 mN/m, a viscosity ... FIG. 1. (Color online) Different craters given by water droplets (size β) impacting a granular layer (sand B) from different initial heights h.
