The solid liquid phase change process in sphere with moving interface was solved using moving heat sources method in convective boundary conditions. The influences of the radius of sphere, the latent heat of material and the convective conditions on phase change process were analyzed. Considering the variational convective conditions in real solid liquid phase change process, a feasible solution is constructed. This solution can be used to validate numerical method and to present necessary comparable data for the experimental results. The method and the calculated results have important practical values for the design and applicationof phase change materials.
