Numerical solutions of mixed convection boundary layer flow near the lower stagnation point of a horizontal circular cylinder 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 horizontal circular cylinder in a stream flowing vertically upwards has been studied for both cases of a heated and cooled cylinder. The resulting system of nonlinear partial...
