Sažetak
The ice block at initial temperature Tis=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 Til=0°C. Six numerical simulations were performed by varying vertical wall temperatures from TW=2 to 12°C (range of Rayleigh number from 4.22x10**6 to 2.28x10**7). 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.
