论文摘要
本文概述了一种数值算法，该算法可通过求解边界积分方程来模拟外部磁场中磁性流体液滴形状的完整3D动力学。该算法可与任意的液滴和载体流体粘度比一起工作。它通过已知的理论关系得到验证。因此，它可以用来评估通过比较从第一原理中从第一原理获得的结果进行比较，以评估椭圆形液滴描述中通常使用的各种近似值。该算法可用于研究任意磁场中的液滴构型，以及间接计算其物理特性，并预测磁场阈值以上液滴形状可以以各种尖峰形式发展不稳定性。
This paper outlines a numerical algorithm that could be used for simulating full 3D dynamics of magnetic fluid droplet shapes in external magnetic fields, by solving boundary integral equations. The algorithm works with arbitrary droplet and carrier fluid viscosity ratios. It is validated with known theoretical relationships. Thus it may be used to evaluate various approximations often used in description of ellipsoidal droplets by comparing droplet dynamics calculated from them to the results obtained numerically from first principles here. The algorithm may be used for investigations of droplet configurations in arbitrary magnetic fields, as well as for indirectly calculating its physical properties and predicting the magnetic field thresholds above which droplet shape can develop instabilities in the form of various spikes.
