Newtonian heating effects on Casson nanofluid flow at lower stagnation point of a solid sphere

Source abstract

Abstract In view of the energy crises, the heat transfer of sodium alginate Casson nanoliquid flow on a lower stagnation point of the sphere is examined in this research. Three types of nanoparticles including Silver (Ag), Titanium oxide (TiO 2 ), and Graphite oxide (GO) Sodium alginate‐based nanoliquid are taken in account for this investigation. Furthermore, magnetic field and Newtonian heating effects are incorporated. The PDEs (flow equations) are converted into ordinary differential equations (ODEs) using nondimensional similarity transformations. Additionally, a well‐known technique known as the Keller box approach is used for numerical solutions. The numerical results are produced in tabulated and graphical form versus the various involved parameters. Furthermore, findings showed that nanoliquid based on graphite oxide has the maximum velocity in view of other nanoparticles (Sodium alginate‐based nanoliquid). Moreover, the variation in magnetic effects decreases the velocity of the nanoliquid flow.
