Popis: An analytical method of the direct contact melting of a two-dimensional arbitrarily shaped solid on an isothermally heated horizontal plate is proposed. To verify the validity of the analytical method, experimental results are also presented for the melting of trapezoidal-shaped two-dimensional ice inclined on an isothermally heated plate. The present analytical results show good agreement with the experimental data, which implies that the present analysis is applicable to study melting of a two-dimensional arbitrarily shaped solid. Three patterns of melting phenomena are observed depending on the aspect ratio of trapezoidal-shaped ice : "stable", "inclined" and "fall-over" melting. It is shown that rapid melting occurs in the case of the stable and the fall-over pattern, in which a position that the How direction of the liquid layer underneath the ice changes is found near the center of ice width.
