| Abstract: | AbstractThe surface energy model, which may govern particle pushing under or near equilibrium solidification conditions, is not valid when convection exists in the liquid. Experiments were carried out to show that under convection conditions, particle pushing occurred at much higher growth rates than that predicted by using the surface energy model. Several mechanisms are proposed for explaining the effects of fluid flow on particle pushing. |
