The melting of a horizontal ice cylinder into a homogeneous calcium chloride aqueous solution in a cylindrical cavity is considered experimentally. Ice cylinder rotates with prescribed several speeds. Melting front mainly shows two kinds of specific configuration depended on the rotating speeds. When the rotating speed is fast, Bamboo nodes appear on the melting front resulting from Taylor vortex flow. On the other hand, when the rotating speed is slow, the melting front shows a specific stripe pattern. This specific melting front configuration appears due to combined effects of both sharkskin and ice cylinder rotation. The melting mass fractions are correlated to the Fourier number and rotating Reynolds number. Quasi-steady Nusselt number is expressed by the Taylor number, concentration Grashof number and some physical properties of the aqueous solution.
