This study investigates a high-flowrate, multi-channel electromagnetic permanent magnet pump (EMP) by comparing experimental and numerical results obtained using an electrical potential (inductionless) method. Experimental data, including pressure, flowrate, power, temperature, and magnet system rotation speed, were collected using EMP in the TESLA-EMP loop at the Institute of Physics, University of Latvia (IPUL) in Salaspils. A numerical calculation under linebreak the same conditions was performed using the COMSOL Multiphysics commercial software. A steady-state MHD calculation, employing the k-ε turbulence model while neglecting the induced magnetic field was performed. The results indicate qualitatively good agreement in the developed pressure under insulating inner wall conditions, suggesting a poor electrical contact between the sub-channels and a relatively low slip magnetic Reynolds number. Figs 9, Refs 4.
