AbstractThe FAST 2.0 model of ice friction was developed for a vertically oriented speed skate. The model is therefore left-right symmetrical about a vertical plane parallel to the sliding direction. It describes ice friction at sliding velocities sufficiently high to produce a lubricating layer of meltwater, which completely separates the ice and slider surfaces. Friction results from ploughing a groove in the ice and from the shear stress in the lubricating Couette flow. The model takes into account frictional melting, heat conduction into the ice and the lateral squeeze flow of the lubricating liquid. Here we present a new, numerical model, FAST 2.0i, which calculates ice friction for an inclined runner that is incising into the ice. Specifically, we consider an inclined speed skate blade and we use it to predict the variation of ice friction during a typical skating stroke. The model results compare favorably with in situ measurements. Copyright © 2012 by the International Society of Offshore and Polar Engineers (ISOPE).
