Résumé

Thermomagnetic devices output power harness the influence of a magnetic field and thermal processes period. In this context, our study aims to conduct a theoretical investigation into the correlation between the amount of magnetic material in the permanent magnet gap and the thermal exchange time between the material and the flowing fluid. A parametric analysis of the magnetic and thermal processes was conducted using COMSOL software, employing a flat plate and cylinder geometries for the magnetic material. Our findings reveal a direct proportionality between the magnetic field and the magnetic force applied to the material, resulting in a higher magnetic energy density with an increased amount of magnetic material in the gap. Concerning thermal exchange processes, a greater quantity of magnetic material leads to an extended duration of thermal exchange. Therefore, a tradeoff was observed between the period of the thermal process and the magnetic energy density supported by the magnet gap.
