導電性磁性流体の基礎的挙動に関する理論的考察 : 第1報,クエット的流れ

抄録

Generally, A conducting magnetic fluids has considerably complex behaviour that depends upon electromagnetic field. Therefore even the fundamental counducting magnetic fluid flow has not been examined enough. In the present paper, a Couette like flow is discussed, which is so important and fundamental for engineering problems. At first, some nondimensional parameters, caused by magnetization are newly defined, and some relations between various nondimensional parameters defined in usual magnetohydrodynamics and parameters newly defined here are given. And the influence of these newly defined parameters on electromagnetic field and on flow field is cleared. Furthermore, a pressure distribution caused by electromagnetic forces is analytically obtained which can not appear in the nonconducting magnetic fluid.
