Simulating Laminar Nanofluid Flow in a Curved Tube Using the Two Phase Approach

Laminar mixed convection heat transfer in a circular Curved tube with a nanofluid consisting of water and 1 vol.% Al2O3 has been studied numerically. Two phase mixture model and control volume technique have been implemented to study flow field. Effects of the diameter of particles on the hydrodynamic and thermal parameters are investigated and discussed. Increasing the solid particles diameter decreases the Nusselt number, while the axial velocity augments. When the particles are in order of nano meter, increasing the diameter of particles, do not change the flow behaviors. The results show that the distribution of solid nanoparticles is uniform and constant in curved tube.
