Summary:Melting of an ice cylinder inside a cylindrical cavity including a calcium chloride aqueous solution is considered experimentally. The ice cylinder rotates with prescribed speeds and cylindrical cavity inclines with prescribed angles. When the inclined angle is small, melting mass of ice cylinder is enhanced by rotation, and melting front shows a specific configuration similar to a “screw”. On the other hand, when the inclined angle is large, melting mass of ice cylinder is reduced by rotation, and melting front shows smooth in spite of rotation of the ice cylinder. We infer that ice cylinder and melted water rotate together due to a viscous force in the case of large inclined angle. Therefore concentration gradient near the melting front becomes small, melting mass is reduced and melting front becomes smooth.
