What is it about?
This work studies numerically the flow and heat transfer of alumina-water nanolfuid in a channel with two facing cavities with discrete heating. The effects of the nanoparticle volume fraction and magnetic field on hydrodynamic and thermal characteristics and entropy generation for assisting/opposing buoyancy have been assessed.

Why is it important?
The results show that the vortex dynamics, heat transfer characteristics and the magnitude of irreversibilities in the entropy generation are strongly affected by the strength of the magnetic field applied and the nanoparticle volume fraction. Moreover, these results suggest that the modulation effect of the applied magnetic field can play an important role in practical applications for entropy generation minimization.
