本文给出了横向磁场作用下导电流体在球形填充床内流动时的压降实验数据。介绍了多孔介质中流动的相关背景信息，并介绍了实验装置和设备的相关细节。的数据进行了介绍和讨论，然后从以前开发的分析模型的预测进行比较。它被发现，良好的协议之间存在的数据时，绘制在无量纲形式。与多孔介质中流体流动的其他方程一样，解析形式在实验确定的常数内指定行为。一个新的常数，桑德斯常数，包含在方程的阻力比，提出。将实验数据与解析模型进行了比较，并对Sanders常数的最佳值进行了估计。
AbstractExperimental data are presented for the pressure drop of a flowing conducting fluid within a packed bed of spheres through a transverse magnetic field. Pertinent background information is presented about flows in porous media followed by relevant details of the experiment apparatus and equipment. The data are presented and discussed and then compared with the predictions from the previously developed analytical model. It is found that good agreement exists between the data when plotted in dimensionless form. As with the other equations for fluid flow in porous media, the analytical forms specify behavior to within an experimentally determined constant. A new constant, the Sanders constant, contained within the equation for the resistance ratio, is proposed. The experiment data are compared with the analytical model, and the best value of the Sanders constant is estimated.
