文档介绍：In order to understand the static ic field under the action of molten droplet oscillation deformation characteristics, the phase field method is adopted to simulate the suspension silicon melt oscillation of the droplet deformation, axial ic field on initial shape are analyzed for the second order Legendre function and fourth-order Legendre function the influence of silicon melt droplet motion and deformation. Results found that: as the silicon melt is bigger, the surface tension of the droplet deformation rapidly. Original shape as the fourth-order Legendre function of droplets, due to its interfacial curvature is small, weak internal flow. ShiJiaJing ic field, ic field part inhibited the droplet flow inside. Along with the increase of the ic field strength inside the droplet convection is abate, the droplets faster shrinkage is spherical. The ic levitation technology is widely apply to measure thermal physical properties of metals and alloys. However, in the process of measuring thermal conductivity , the convection and oscillation due to the surface tension of the melt can lower the accuracy of measurements . Therefore, it is necessary to reduce internal convection of melt in some cases . Yasuda adopt s the method of applying alternating ic field and static ic field at the same time, observe the different strength under the static ic field, ic levitation melt oscillation pro
