Background • Induction pumps work well for highly conductive

fluids such as liquid metals

• Useful when pumping liquid metals in high temperature cooling systems

• The lack of moving parts is a major advantage

Modeling Approach • 2D axial symmetry, periodic cell of larger coil system

• Magnetic Fields, frequency domain + Laminar Flow,

stationary

• Couple the cycle average Lorentz forces (JxB) to Laminar Flow

• Couple the fluid velocity field to Magnetic Fields
