Abstract
In this study, both Newtonian and non-Newtonian Nano-fluids are used to look into heat transfer and fluid flow. The objective of this study is to examine the interaction between fluids and permeable surfaces in the presence of a magnetic field. Specifically, the study focuses on the behavior of cassion fluids, the occurrence of chemical reactions, as well as the processes of injection and suction. The research employs the approach of similarity solutions to convert partial differential equations into ordinary differential equations, which are subsequently solved numerically using the Runge-Kutta-Fehlberg fourth-fifth order (RKF45) method. This study investigates the utilization of Cu, CuO, TiO2 and Al2O3 nanoparticles within a sodium carboxymethyl cellulose and water base fluid. The analysis focuses on key parameters such as power-law index, nanoparticle volume percentage, and permeability to assess the influence of these factors on the flow and heat transfer properties of the Nano fluid.
The findings of the study demonstrate that the flow and heat transfer characteristics of non-Newtonian Nano fluids are significantly affected by the presence of suction and injection, leading to discernible patterns of behavior. In the context of injection settings and impermeable plates, it has been observed that non-Newtonian Nano fluids have superior heat transfer capabilities compared to Newtonian Nano fluids. Nevertheless, the alteration in nanoparticle composition has a substantial influence on heat transmission during the process of suction.
