| Summary: | To fill the existing literature gap, the numerical solutions for the oblique stagnation-point flow of Cu-Al2
O3
/H2
O hybrid
nanofluid past a shrinking surface are computed and analyzed. The computation, using similarity transformation and
bvp4c solver, results in dual solutions. Stability analysis then shows that the first solution is stable with positive smallest
eigenvalues. Besides that, the addition of Al2
O3
nanoparticles into the Cu-H2
O nanofluid is found to reduce the skin friction
coefficient by 37.753% while enhances the local Nusselt number by 4.798%. The increase in the shrinking parameter
reduces the velocity profile but increases the temperature profile of the hybrid nanofluid. Meanwhile, the increase in the
free parameter related to the shear flow reduces the oblique flow skin friction. |
