An analytic solution of conduction heat transfer in a menisus enclosure of planar geometry was obtained by conformal mapping. The numerical study of natural convection heat transfer in both planar and spherical meniscus-shaped enclosure was also conducted to find an emprical relation for the heat transfer coefficients. A concise correlation to predict the Nusselt number at a top point of the lower surface was presented in terms of the size of the geometry and Rayleigh number. The present results then were applied to the analysis of contact melting process in a horizontal cylinder, focusing on the better estimation of the role of natural convection heat transfer in the melt pool. When compared with the avaiable experimental results, the predicted melt volume fraction was found to overestimate. The present investigation revealed that the natural convection in the melt pool affected more the melting behavior than was observeded in the experimental results.
