Design of an Electromagnetic Pump and Numerical Analysis of the Liquid Metal Flow

An electromagnetic pump has been designed using Load Distribution Method and Equivalent Circuit Method, and installed in a liquid metal flow system. The relation between the driving power of he electromagnetic pump and the flow rate was proposed. Also, the flow velocity and flow rate has been calculated by treating the Lorentz force as a source term in the Navier-Stokes equation. The calculation results were analyzed and compared with data from a commercial Code, FLUENT. They agreed well with each other within an error of 5%.
