AB - The fluid flow and heat transfer characteristics and entropy generation of  zirconia, ZrO2-water, nanofluid flow through a rectangular micro-channel are  numerically investigated. The flow is considered under single-phase 3-D  steady-state incompressible laminar flow conditions. The constant heat flux  is applied to the bottom surface of micro-channel. The finite volume method  is used to discretize the governing equations. As a result, the average  Nusselt number decreases with increasing nanoparticle volume fraction, while  the average Darcy friction factor is not affected. Moreover, the total  entropy generation decreases with increase in nanoparticle volume fraction,  while the Bejan number is almost not affected.
