摘要

In present study, a steady, two-dimensional, laminar boundary layer flow of viscous and incompressible fluids (water, Cu/water nanofluid, and Al₂O₃-Cu/water hybrid nanofluid) along a permeable stretching wedge under the effect of inclined magnetic field is investigated. The effects of viscous dissipation, Newtonian heating, and Joule heating are also considered. The governing equations of this flow are converted into non-linear ordinary differential equations with the help of similarity transformations and then converted in a system of first-order ODEs. This system along with boundary conditions is solved numerically using bvp4c method of MATLAB. The impacts of magnetic field and its inclination angle, wedge angle, porosity, Newtonian heating, joule heating and suction on velocity and temperature profiles are presented graphically and discussed in detail. This study demonstrates that hybrid nanofluid exhibits a higher heat transfer rate and skin friction compare to the nanofluid while the nanofluid in turn outperforms the base fluid in these properties. The findings indicate that the inclination of magnetic field boosts fluid velocity and temperature while increase of key parameters along with incorporation of nanoparticles positively influences heat transfer rate and shear stresses and it is also observed that using more non-spherical nanoparticles increases the nanofluid’s thermal conductivity and enhances microscopic mixing which causes higher fluid velocity and temperature. Additionally, shear stresses and heat transfer also increase as shape factor increases. This study can be useful in oil recovery from porous rocks, groundwater remediation, polymer processing, liquid metal casting, magnetic drug targeting through porous tissues, etc.
