Impact of Buoyancy and Stagnation-Point Flow of Water Conveying Ag-MgO Hybrid Nanoparticles in a Vertical Contracting/Expanding Riga Wedge

Abstract

Riga surface can be utilized to reduce the pressure drag and the friction of the submarine by stopping the separation of the boundary layer as well as by moderating turbulence production. Therefore, the current symmetry of the work investigates the slip impacts on mixed convection flow containing water-based hybrid Ag-MgO nanoparticles over a vertical expanding/contracting Riga wedge. In this analysis, a flat surface, wedge, and stagnation point are also discussed. A Riga surface is an actuator that contains electromagnetic where a span-wise array associated with the permanent magnets and irregular electrodes accumulated on a smooth surface. A Lorentz force is incorporated parallel to the surface produced by this array which eases exponentially normal to the surface. Based on the considered flow symmetry, the physical scenario is initially modeled in the appearance of partial differential equations which are then rehabilitated into a system of ordinary differential equations by utilizing the pertinent similarity variables. A bvp4c solver is engaged to acquire the numerical solution. The flow symmetry and the influences of pertaining parameters involved in the problem are investigated and are enclosed in graphical form. The findings confirm that the velocity reduces, and temperature enhances due to nanoparticle volume fraction. A modified Hartmann number increases the velocity and diminishes the temperature. Moreover, the suction parameter enhances the velocity profiles and reduces the dimensionless temperature profiles. The heat transfer gradually increases by diminishing the contracting parameter and increasing the expanding parameter.

Numerical solution and statistical analysis of the unsteady hybrid ferrofluid flow with heat generation subject to a rotating disk

“…They revealed that the addition of nanoparticles volumetric concentration diminished the blood velocity and temperature profiles. The discussions regarding the thermal and flow characteristics of hybrid nanofluids were reported by Khashi'ie et al [21][22][23][24] for disc case, Khan et al [25][26][27] for wedge and cylinder geometries and Lund et al [28][29][30][31] for stretching/shrinking plate. The hybrid nanofluid flow subjected to the unsteadiness decelarating case was analyzed by Zainal et al [32][33][34][35][36] for various geometries.…”
