Abstract

Our study focused on modeling the extraction of cations from paramagnetic fluids. The paramagnetic fluid flows within a rectangular cavity whose lower and upper parts are subjected to hot Tc and cold Tf temperatures, respectively. The other walls were adiabatic. The cavity is also influenced by an external magnetic field, b0.• The thermal input highlights heat transfer by convection.• The external magnetic field induces excitation and de-excitation of the cation, promoting quantum jumps in the particle.Thus, we were able to highlight the influence of temperature and magnetic fields on the flow velocity. We combined the Navier–Stokes equations with quantum mechanics for modeling. We carried out a simulation of the paramagnetic fluid flow, allowing us to evaluate the cation ejection velocity at the cavity outlet for its extraction.
