The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.
