| 中文摘要 | 磁流体（MHD）推进是一种新型的船舶推进方式.该文对交流磁流体推进进行了较为全面和深入的研究,以期为交流磁流体推进器的设计制造提供理论和试验方面的准备,并为今后中国发展交流磁流体推进系统打下较为坚实的基础.该文的主要内容如下：全面系统地介绍了交流磁流体推进的发展历史和国内外研究现状.从电磁场和流体力学的理论出发,建立了交流磁流体推进系统的二维数学模型.在此基础上,对平面型内磁式交流磁流体推进器的电磁场和流场的所形成的二维耦合场进行了仿真分析.用仿真的方法验证了日本佐治吉郎教授等人在20世纪90年代所做的旋转超导磁体交流磁流体推进试验,取得了令人满意的结果. As a new type of ship propulsion, AC Magnetohydrodynamic(MHD) propulsion apply alternating magnetic field through seawater, then a Lorentz force will act to move the seawater and thus drive the ship to move. The system eliminates the conventional rotating driving components, the absence of mechanical propeller system will lead to a reduction in the mechanical noise generated and make the arrangement of ship more expedient. Compared with DC-MHD propulsion, AC mode has no electrode and doesn't apply electric field to fluid directly. Thus it avoids the detriment and noise caused by the air bubble generated by electrolysis, and makes the ship more quietly. These characters will help to develop a more efficient ship thruster. In order to provide the theoretical and experimental guides for the design and fabrication scheme of the engineering prototype of AC-MHD propulsion in the future, this thesis is focused on the following researches related to the AC-MHD propulsion. A general review on the development and current situation of the AC-MHD propulsion is presented. With the theory of electromagnetic field and the theory of hydrodynamic, a 2-D mathematics model of internal planar AC-MHD thruster is built. On the basis of mathematics model, the coupled field of alternating magnetic field and fluid field in the channel of a 2-D AC-MHD thruster is simulated using finite element method. To verify the result of the experiment by Yoshiro Saji in 1990's, the author try to calculate the simplified 2-D coupled field of the tester, and get a satisfied result. |
