Využití MHD čerpadel tekutých kovů pro chlazení vysokoteplotních jaderných reaktorů
Doležel, Ivo ; Donátová, M. ; Karban, P. ; Ulrych, B.
MHD pumps represent prospective devices without movable parts that may be used for pumping molten metals instead of classical rotational pumps. The paper analyses the possibilities of their employment for pumping molten lead as cooling medium in nu-clear reactors of the fourth generation.
Možnosti elektromagnetického čerpání tekutých kovů a jejich numerické modelování
Musil, Ladislav ; Doležel, Ivo ; Karban, P. ; Ulrych, B. ; Barglik, J.
Electromagnetic pumps and feeders of molten metals are widely spread devices used in many branches of industry. Their operation is, however, accompanied by a high consumption of energy. Im-provement of their efficiency and optimization of their design requires detailed knowledge of the relevant electromagnetic (and sometimes also thermo- and hydrodynamic) processes. The paper deals with the principles of operation of such devices, presents their mathematical models and techniques of their numerical solu-tion. The theoretical analysis is illustrated on typical examples providing the fundamental ideas about their operation parameters and characteristics.
