In this paper, an analysis is made on the convective heat transfer of a nanofluid between two inclined parallel plates with a uniform heat flux boundary condition. The analytical solutions are obtained explicitly for the velocity, temperature, and pressure distributions, which are dependent on two parameters P 1 and P 2 . By alerting their values, four different regimes for flow reversal are found. On the other hand, it is found that the nanoparticle volume fraction / has a significant influence on the flow reversal. Physically important quantities such as wall friction and Nusselt number are in detail discussed for the TiO 2 -water nanofluid.
