One of the main purpose of the group for research on magnetic fluid was to organize the 4th International Conference on Magnetic Fluids. Activities of the group have been crowned with great success. The papers presented in the conference was published in Journal of Magnetism and Magnetic Materials Vol.65(1987),173-445, as the proceedings of the conference. The amount of presentation concerned with the research project in our group reached 15. Also, the members of the group played leading parts in the internal meeting of magnetic fluid engineering held in December 1987 and carried out a summary of research for 2 years.The results concerned with this research project are as follows:(1) In the research field of the preparation and properties of magnetic fluids, a preparation method of a magnetic fluid composed of metalic particles which have excellent properties drew attention. Also, the studies of aggromeration phenomenon of magnetic particles in a strong magnetic field and an optical characteristic of a particle have been advanced.(2) In the field of the fundamental studies of the magnetic fluid dynamics, new governing equation system of magnetic fluid was proposed. Also, it would be noticed that the possibility of new developments of magnetic fluid dynamics has been raised since the research into the steady and unsteady flow characteristics in a pipe and the instability of fluid surface has remarkably progressed.(3) In the field of the applications of magnetic fluids, fruitful results have been obtained regarding the improvement of the performance of magnetic fluid seals. In addition, new progresses were reported in the applications of the magnetic fluid such as damper, actuator, grinding device, energy coversion system development and medical treatment.

磁流体研究小组的主要目的之一是组织第四届国际磁流体会议。该小组的活动取得了巨大成功。会议论文发表在《磁学与磁性材料学报》第65卷（1987），173 -445页，作为会议论文集。我们组与研究项目有关的报告达到了15篇。在1987年12月召开的磁流体工程学内部会议上，课题组成员也发挥了主导作用，并对2年来的研究工作进行了总结，与本课题有关的研究结果如下：（1）在磁流体的制备和性能研究领域，一种由具有优良性能的金属颗粒组成的磁流体的制备方法引起了人们的注意。此外，对磁性粒子在强磁场中的聚集现象和粒子的光学特性的研究也取得了进展。(2)在磁流体动力学基础研究领域，提出了一种新的磁流体控制方程组。另外，由于对管道中的定常和非定常流动特性以及流体表面的不稳定性的研究取得了显著进展，这也为磁流体动力学的新发展提供了可能性。(3)在磁流体的应用领域，人们在提高磁流体密封性能方面取得了丰硕的成果。此外，还介绍了磁流体在阻尼器、执行器、磨削装置、能量转换系统开发和医疗等方面的应用新进展。
