Mixed convection boundary layer flow near the lower stagnation point of an isothermal solid sphere in a nanofluid

In this paper, the problem of steady mixed convection boundary layer flow in a nanofluid near the lower stagnation point of a solid sphere in a stream flowing vertically upwards has been studied for both cases of heated and cooled spheres. The resulting system of nonlinear partial differential equat...
