From **Table 2**, the numerical values of the skin-friction and the local Nusselt number are given in **Table 2**. For an increase in the magnetic field parameter *M*, we observe that the skin-friction coefficient along *x*- and *y*-directions and the local Nusselt number decrease when *c* = 0.5, but at *c* = �0.5, the skin-friction coefficient along *x*-direction and the local Nusselt number decrease, while the skin-friction coefficient along *y*-direction increases. While, with an increase in the porous medium parameter *S*, we observe that the skin-friction coefficient and the local

With an increase in nanoparticle volume fractions *φ*, we observe that the skinfriction coefficient increases and the local Nusselt number increases when *c* = 0.5, but at *c* = �0.5, the skin-friction coefficient along *y*-direction and the local Nusselt number decrease, while the skin-friction coefficient along *x*-direction increases. While, with an increase in the thermal radiation parameter *Q*, we observe that the

In the present chapter, the magnetohydrodynamic effects on heat transfer and thermal radiation at a stagnation point flowing in a nanofluid containing different types of nanoparticles namely, copper (Cu), alumina (Al2O3) and titania (TiO2) through a porous medium have been investigated numerically. By using appropriate transformation for velocity and temperature into a set of non-linear coupled ordinary differential equations which are solved numerically, the governing equations were:

1. With the increasing values of the magnetic field parameter, porous medium parameter and nanoparticle parameter, it is observed that the velocity profile
