IRREVERSIBILITY ANALYSIS OF MHD RADIATIVE FLOW IN A POROUS CHANNEL WITH DIFFERENT NANOPARTICLES

What is it about?

The entropy generation on radiative heat transfer performance in the flow of variable thermal conductivity optically thin viscous water-based nanofluid with an external magnetic field through a porous parallel channel is investigated in the present work. Three types of nanoparticles as Cu, TiO2 and Al2O3 are used to observe their performance. The fluid temperature in the channel varies due to the asymmetric heating of the walls as well as viscous dissipation.

Why is it important?

It is observed that suction/injection of fluid exerts a significant influence on the velocity and temperature distribution, which transitively affects the entropy generation within the channel.
