Abstract :
This paper presents a coupled model of linear induction pump for liquid metal. The model computes the magnetic field in the motionless domains by a finite-element method and calculates the field inside the moving parts by Fourier transform and spectral projection on a Hermite basis. The paper focuses on the analysis of the force density according to the current supply and speed variations.
