摘要：This research presents the stagnation point flow with heat transfer of water-based hybrid nanofluid over a stretching/shrinking wedge. Magnetic field is applied normal to the wedge with melting heat transfer effect. The wall of the boundary with slip effect on the surface. Water as base fluid with two different nanoparticles (Al2O3 and Cu) is considered. The Navier-Stokes and heat equation are first simplified through similarity variables to convert the partial differential equations (PDEs) into non-dimensional ordinary differential equations (ODEs). The numerical solutions are obtained with the help of bvp4c technique in MATLAB programming. This study is focused on the impacts of different dimensionless parameters on the velocity field, temperature distribution, skin friction coefficient and Nusselt number. It is seen that the solution of governing ODEs has two branches, first and second branch solutions in some specific range of supervising parameters. It is found that heat transfer rate enhances against melting parameter in the first branch solution and converse behavior can be observed for second branch solution. It is also uncovered that in hybrid nanofluid, the momentum and thermal boundary layer thickness enhances in first solution while reduces in the second solution with the advancement of angle of wedge parameter.
