高频磁场下铝基复合材料熔体中颗粒相的受力与迁移行为模拟
Simulation on force and movement behavior of particles in aluminum matrix composite melt under high-frequency magnetic field
摘要
Abstract
According to the basic principles of electromagnetic, the magnetic flux density on the surface of the metal melt was calculated through numerical simulation method. The relational expression of the electromagnetic body force and the magnetic flux density was deduced. Furthermore, the relational expressions of the velocity of particle migration, the angle of the particle migration offset and the electromagnetic body force were deduced. The results show that the main influential factors of particle migration behavior include the current intensity, frequency and particle size. The effect of the height on electromagnetic body forces is from 20 mm to 100 mm. Especially the electromagnetic body force reaches the maximum value at 80 mm. With the increase of the current intensity, the distribution of particles along the height direction becomes more uniform.关键词
