An electromagnetic pump using tubular induction motor (TLIM) has been proposed to pump liquid metal fluids. TLIM has been designed for the liquid metal flow system with motor thrust force of about 40∼77 N. The flow characteristics have been investigated by solving Navier-Stokes equation. The Lorentz force effect was included simply by considering it as a constant source term in the Navier-Stokes equation. A wood-metal was chosen for the simulation of liquid metal. The effect of Lorentz force on the flow rate was investigated. Also, in order to verify the analysis results, an experiment was conducted and the experimental results were compared with those of the simulation. The simulation results showed over-estimation of about 10% compared with the experimental ones.
