摘要：
A numerical analysis was carried out to study the moving boundary problem in thephysical process of pulsed Nd-YAG laser surface melting prior to vaporization.The enthalpy methodwas applied to solve this two-phase axisymmetrical mehing problem.Computational results of temperature fields were obtained,which provide useful information to practical lair treatment processing.The validity of enthalpy method in solving such problems is presented.
