中文摘要: 本文根据Maxwell电磁学基本方程和混沌理论[1],结合有限元法,设计了一款新型基于直流励磁的电磁搅拌装置,建立了直流电磁搅拌装置在工作时的多场耦合三维数值模型。采用ANSYS软件对磁场和流场的分布形态特征进行了数值模拟分析[2]。发现在电磁搅拌时,交变磁场能够形成周向电磁力,通过该力促使有色金属熔体进行运动,发现熔体内部的循环流以及槽壁附近剪切流是相互冲突的,这种现象为有色金属和增强基相互碰撞、摩擦、混合创造了有利条件。
Abstract:In the melting process of non-ferrous metals, melt stirring is one of the most important processes. According to the basic equation of Maxwell electromagnetics and chaos theory, combined with finite element method, a new electromagnetic stirring device based on DC excitation is designed in this paper, and the three-dimensional numerical model of multi-field coupling of DC electromagnetic stirring device is established. The distribution and morphological characteristics of magnetic field and flow field are simulated and analyzed by ANSYS software. During electromagnetic stirring, the alternating magnetic field can form the circumferential electromagnetic force, through which the non-ferrous metal melt can move. It is found that the circulating flow inside the melt and the shear flow near the groove wall are in conflict with each other. This phenomenon creates favorable conditions for the collision, friction and mixing of non-ferrous metals and reinforcement groups.
