| 摘 要： | 将行波磁场理论和流体运动N-S方程相结合,建立了行波磁场作用下材料制备用容器内三维流场的数学模型,并引入了新的电磁力计算模型.通过与文献中实验结果的对比,验证了本模型及计算程序的可靠性.研究还发现,行波磁场作用下装置内纵截面形成了两个对称的大环流;当径高比降低时,容器内的流场结构没有改变,仍然为两个对称的旋流,形状由椭圆形变成长方形.当电磁力增大时,轴向速度曲线由平顶变为尖顶的抛物线,并且电磁力越大,波顶离底部壁面的距离越近.

| Abstract: | Combining the theory of traveling magnetic field with the Navier-Strokes equation for fluid motion,a mathematical model was developed for the 3-D flow field in a cylindrical container to prepare metallic materials under the action of traveling magnetic field.In addition,a new model was introduced to compute the electromagnetic force.It was found through comparison that the modeling results is in accord with the experimental results made by Gerbeth,thus verifying the reliability of the model developed and re... |
