A Combined Convection Carreau–Yasuda Nanofluid Model over a Convective Heated Surface near a Stagnation Point: A Numerical Study

Abstract

The focus of this manuscript is on two-dimensional mixed convection non-Newtonian nanofluid flow near stagnation point over a stretched surface with convectively heated boundary conditions. The modeled equation representing nonlinear flow is transformed into a system of ordinary differential equations by implementing appropriate similarity transformations. The generated structure is numerically solved by applying the bvp4c method. Consequences of various involved parameters, e.g., stretching parameter, mixed convection parameter, thermophoresis parameter, Brownian movement parameter, Lewis number, Weissenberg number, Prandtl number, Biot number, buoyancy ratio parameter, mass and heat transport rates on temperature and velocity, the stretched surface, and nanoparticle concentration patterns are analyzed. Outcomes are shown graphically and displayed in tables. Velocity fluctuations are responded to by growing parameters of mixed convection and Weissenberg number. Concentration and thermal fields are also discovered for the Prandtl number. There are also flow line diagrams to analyze the behavior.

Design of Spline–Evolutionary Computing Paradigm for Nonlinear Thin Film Flow Model

“…Non-Newtonian viscous fluid flow modelling equations arise to strongly nonlinear systems. The non-Newtonian liquids are widely used in trade and industry and now have become the subject of comprehensive research, particularly mixed with nanomaterials [21][22][23][24][25][26][27][28]. For instance, chemical industries handle polymers and plastics extensively, whereas rheological activity is used by biomedical devices such as homodialyser.…”
