摘要：
A numerical simulation has been used to determine the changes in shape of a solidification front approaching a particle with a thermal conductivity different from that of the liquid. Calculations have been done for nylon, steel and glass spheres in an ice-water system. The results are in good agreement with the experimental observations described in a previous paper. Some applications of the determination of the front shape (evaluation of the forces acting on the particle, isoterms around the particle are also presented.
