A comparative analysis of the magnetized sodium alginate-based hybrid nanofluid flows through cone, wedge, and plate

Abstract

The heat transmissions of magnetohydrodynamic nanofluid flow through the cone, wedge, and plate have many industrial and commercial applications. The cone, wedge, and plate geometries are widely used in polymer data processing. That is why the authors have chosen to analyze the heat transmission of a hybrid nanofluid flow over multiple geometries. The hybrid nanofluid flow contains copper and silver nanoparticles, whereas sodium alginate is used as a base fluid. The impacts of thermal Grashof number, magnetic parameter, thermal radiation, and the Chataneo–Christov heat flux model are taken into consideration. The generated system of differential equations is solved with the help of homotopy analysis method (HAM). The convergence of HAM is also shown with the help of figures. Validation of current findings with previously reported findings over a cone surface has been analyzed and has found a great agreement with those reported results. The results showed that the temperature Grashof number reduces skin frictions while the augmenting magnetic parameter increases them. When compared to cone and plate geometry, these effects are more prominent for wedge geometry. Also, the impact of magnetic factor is 38% greater and the thermal Grashof number is 47% greater for hybrid nanofluid flow than the base fluid. The heat transfer rates are reduced with the increasing thermal relaxation and wall temperature parameters. The thermal relaxation is 4% greater and the wall temperature parameter is 14% greater for the hybrid nanofluid flow than the base fluid. The velocity profiles are decreased with the increasing magnetic parameter. The decreasing impact is larger for plate surface in comparison to the wedge and cone.
