  This paper studies the effects of mixed convection fluid motion and heat
transmission of Al2O3-Water nanofluid in a square enclosure including two
heated obstacles, with temperature and nanoparticle concentration being
determined by the thermal conductivity and effective viscosity. The parametric
observations of Richardson number, Reynolds number, cylinder rotating speed,
and cavity inclination angles are investigated in the range of 0.1 \leq Ri \leq
10, 1 \leq Re \leq 125, 1 \leq \omega \leq 25, and 0^\degree \leq \gamma \leq
60^\degree respectively on the thermal environment and flow arrangement inside
the cavitation field. Adding nanoparticles to the base fluid enhances the heat
transfer rate for both obstacles and all ranges of the parameters. The
influence of wavy walls, changes in the nanofluid, and distinct positional
effects also impact the flow characteristics and heat transfer process.
