Scrutinization of 3D flow and nonlinear radiative heat transfer of non-Newtonian nanoparticles over an exponentially sheet

Purpose This paper aims to explore the consequence of chemical reaction on three-dimensional flow, heat and mass transfer of a Casson nano liquid over exponentially stretching surface. A numerical technique of RKF-45 method is applied to resolve the nonlinear ordinary differential equations, which are obtained by applying the similarity transformation to the nonlinear partial differential system. Design/methodology/approach Role of significant parameters on flow fields are observed graphically. Also, the strength of heat exchange (Nusselt number) and the strength of mass exchange (Sherwood number) are analyzed. Findings The results of numerical modeling showed that, the Prandtl number plays a key role in reducing the temperature of the system. Further, the radiation parameters manufacture a lot of heat to operating fluid and higher temperature exponent parameter and enhance the temperature of the fluid. Originality/value The results of numerical modeling showed that, the Prandtl number plays a key role in reducing the temperature of the system. Further, the radiation parameters manufacture a lot of heat to operating fluid and higher temperature exponent parameter and enhance the temperature of the fluid.
