Abstract

The results of theoretical and experimental studies of convective vortex currents formed during ice melting, as well as physical modeling of the phenomenon of spontaneous rotation of an ice disk on the water surface, are presented. It is shown that the cause of the observed movements on the surface of initially quiescent water is a cellular convective flow generated by the process of ice melting at the lower boundary of the disk, and a new physical model of such rotation is constructed.
