Nonlinear Thermal Radiation and Chemical Reaction Effects on a (Cu-CuO)/NaAlg Hybrid Nanofluid Flow Past a Stretching Curved Surface

The boundary layer flow of sodium alginate (NaAlg) based (Cu - CuO) hybrid nanofluid, over a curved expanding surface, has been investigated. Heat and mass transport phenomena have also been analyzed. Moreover, the impacts of chemical reaction, magnetic field and nonlinear thermal radiation are also a part of this study. This arrangement has great practical relevance, especially in the polymer and chemical industries. We have extended the Bruggeman model to make it capable of capturing the thermal conductivity of (Cu - CuO)/NaAlg hybrid nanofluid. We have employed some suitable transformations to obtain the governing system of nonlinear ODEs. Runge-Kutta-Fehlberg algorithm, accompanied by a shooting technique, has been employed to solve the governing system numerically. The changes in the flow and heat transfer distribution, due to various parameters, have been captured and portrayed in the form of graphs. It has been found that the addition of the nanometer-sized materials, significantly boosts the thermal and heat transport properties of the host fluid, and these phenomena seem to be more prominent, in the case of (Cu - CuO)/NaAlg hybrid nanofluid.
