The presented work is a computational study of magnetohydrodynamic flow and heat transfer in the Graëtz heat exchanger with insulating walls in a stable laminar regime under specific temperature conditions at the walls. In all simulations, a numerical method is employed based on finite volume technique. We modelled the process to determine features related to the MHD heat transfer in the Graëtz systems. The combined effect of the magnetic field and plate inclination angle was examined, i.e. under the angular effect on liquid silicon flow, heat and momentum transfer with variable values of the transverse magnetic field strength. The obtained results show that heat transfer is weakly (19
