This study examines the behavior of Non-Newtonian Nano fluids in fluid flow and heat transfer over a permeable surface with injection and suction. The governing equations are converted into ODE using a similarity approach and solved numerically with the RKF45 method. Cu, CuO, TiO2, and Al2O3 nanoparticles are used in (CMC)/water as the base fluid to investigate the effects of power-law index, nanoparticle volume fraction, type, and permeability factor. The results indicate that Non-Newtonian nanofluids exhibit different behavior than Newtonian nanofluids in the presence of suction and injection. Non-Newtonian nanofluid performs better than Newtonian nanofluid in terms of heat transfer for injection and an impermeable plate, but changing the type of nanoparticles has a larger effect on heat transmission during suction. Additionally, using Non-Newtonian nanofluid in injection reduces heat transmission in all
Three cases. The study's findings provide useful insights into the behavior of Non-Newtonian nanofluids for practical applications. Moreover, it is observed that the heat transfer rate is enhanced with increasing injection, whereas it is reduced with increasing suction. The results of the study could be useful for designing efficient heat transfer systems involving Non-Newtonian nanofluids over permeable surfaces with injection and suction.
