The current work is aimed at numerical investigation and analysis of entropy generation thermal efficiency Fe₃O₄/water nanofluids flowing through a heat exchanger considering multiple identical magnetic sources. simulated domain corresponds to minichannel heated from below constant temperature, while its upper wall adiabatic. Numerical simulations were carried out using the finite volume method (FVM). To determine new thermophysical properties nanofluid, single-phase approach was adopted. obtained results are presented as Nusselt number, streamlines, isotherms, generated with other relevant parameters, namely, field strength, number magnet pairs, range Reynolds numbers, volumetric fraction nanoparticles. revealed that these parameters significantly influence transfer mechanism. Selecting carefully crucial for achieving enhanced and, consequently, desirable improvement in transfer.
