摘      要：Using the advanced algorithm combining parallel computing,adaptive mesh re-griding and multigrid methods,quantitative 3D phase-field simulations of non-isothermal solidification of binary alloy were carried *** 3D phase-field simulation results were compared with the analytical LKT(Lipton,Kurz and Trivedi)*** comparison,the simulation and analytical results for 2D cases were also *** 3D phase-field simulation results support the transport portion of the LKT ***,the tip radius and tip velocity predicted by the simulations are not in good agreement with the LKT theory over the whole range of *** stability parameter calculated from phase-field simulations varies significantly with the Peclet number,indicating that the stability criterion,which assumes that the stability parameter is constant,is invalid.
