Liquid alloy systems have a high degree of thermal conductivity, far superior to ordinary nonmetallic liquids and inherent high densities and electrical conductivities. This results in the use of these materials for specific heat conducting and dissipation applications for the nuclear and space sectors. Uniquely, they can be used to conduct heat and electricity between nonmetallic and metallic surfaces. | First studies for the development of computational tools for the design of liquid metal electromagnetic pumps N u c l e a r E n g i n e e r i n g a n d T e c h n o l o g y 4 9 ( 2 0 1 7 ) 8 2 e9 1 Available online at ScienceDirect Nuclear Engineering and Technology journal homepage: Invited Article First Studies for the Development of Computational Tools for the Design of Liquid Metal Electromagnetic Pumps Carlos O.

Uniquely, they can be used to conduct heat and electricity Accepted 16 July 2016 between nonmetallic and metallic surfaces. The motion of liquid metals in strong magnetic Available online 30 July 2016 fields generally induces electric currents, which, while interacting with the magnetic field, produce electromagnetic forces. Electromagnetic pumps exploit the fact that liquid metals Keywords: are conducting fluids capable of carrying currents, which is a source of electromagnetic ALIP fields useful for pumping and diagnostics. The coupling between the electromagnetics and Electromagnetic Pumps thermo-fluid mechanical phenomena and the determination of its geometry and .
