Thermal analysis of rotating system with porous plate using nanofluid

In this study homotopy perturbation method is used to investigate nanofluid flow and heat transfer between two horizontal plates in a rotating system. The lower plate is a stretching sheet and the upper one is a solid porous plate. Copper (Cu) as nanoparticle and water as its base fluid have been considered. Comparison between HPM and numerical solution results showed an excellent agreement. The results for the flow and heat transfer characteristics are obtained for various values of the nanoparticle volume fraction, suction/injection parameter, rotation parameter and Reynolds number. The results show that for both suction and injection, the heat transfer rate at the surface has direct relationship with nanoparticle volume fraction, Reynolds number and injection/suction parameter but it is a decreasing function of power of rotation parameter.
