Résumé

The ice block at initial temperature (0°C) is fixed at the center of a long, prismatic enclosure with isothermal vertical walls and insulated horizontal walls. The enclosure is completely filled with water at initial temperature (0°C). Six numerical simulations were performed by varying vertical wall temperatures from TW= 2 to 12°C. In the case of TW >8°C the ice melts faster from above and for TW <8°C from below. In the case of TW= 8°C, two vortices are separated by nearly vertical 4°C isotherm and the average Nusselt number remains constant during the convection dominated regime.
