| Abstract: | Freezing/melting of water/ice around a horizontal cylinder placed in a square cavity of the inner side length H is investigated numerically. The cylinder is fixed at the centerline of the cavity and placed at various vertical distances of h = H/3, H/2 and 2H/3 from the bottom. Melting decreases considerably with increasing cylinder distance h. Freezing shows the utmost effect at h = H/2, other locations h = H/3 and h = 2H/3 will considerably retard freezing. |
