Magnetohydrodynamics mixed convective flow driven through a static wedge including TiO2 nanomaterial with micropolar liquid: Similarity dual solutions via finite difference method

Abstract

This research scrutinizes the influence of titanium oxide (TiO2) nanoparticle on electrically conducting micropolar liquid driven through wedge with mixed convection and thermal radiation. Buoyancy opposing flow and buoyancy assisting flow are taken into consideration. Similarity parameters are employed to transmute the governing partial differential equations into ordinary differential equations and then obtained the dual solutions through finite difference method. Impacts of ensuing parameters on liquid velocity, temperature distribution, and microrotation field are described and argued. Dual solutions are realized in buoyancy opposing flow, whereas in buoyancy assisting flow outcome is unique. Nanoliquid velocity tends to decline in the first solution and enhances in the second solution due to nanoparticle volume fraction, whereas microrotation profiles increases in both solutions. Temperature distribution increases in the first solution and decreases in the second solution due to φ. Due to micropolar parameter, the velocity and microrotation profiles decrease in both solutions, whilst the temperature of fluid behaves in opposite manner. Results also showed that separation of boundary layer can be controlled through micropolar parameter and nanoparticle volume fraction. In addition, support of present outcomes is arranged through benchmarking by previous well-known limiting conditions and pledged that a fabulous agreement with these results.
