Abstract
Melting of a vertical ice cylinder into a homogeneous calcium chloride aqueous solution inside a rotating cylindrical cavity with several revolution speeds is considered experimentally. Melting mass and temperature are measured on four initial conditions of the solution and four rotating speeds of the cavity. Temperature of liquid layer becomes uniform by the mixing effect resulting from cavity rotation and it enhances the melting rate of ice cylinder. As cavity-rotating speed becomes fast, melting rate increases. Dimensionless melting mass is related to Fourier number and rotating Reynolds number in each initial condition, therefore the experimental equation that is able to quantitatively calculate a dimensionless melting mass is presented. It is seen that melting Nusselt number re-increases in the middle of melting process. Ice cylinder continues to melt in spite of small temperature difference between ice cylinder and solution.
