AB - The non-linear Navier-Stokes equations governed on the nanofluid flow  injected through a rotary porous disk in the presence of an external uniform  vertical magnetic field can be changed to a system of non-linear partial  differential equations by applying similar parameter. In this study, partial  differential equations are analytically solved by the modified differential  transform method, Pade differential transformation method to obtain  self-similar functions of motion and temperature. A very good agreement is  observed between the obtained results of Pade differential transformation  method and those of previously published ones. Then it has become possible to  do a comprehensive parametric analysis on the entropy generation in this case  to demonstrate the effects of physical flow parameters such as magnetic  interaction parameter, injection parameter, nanoparticle volume fraction,  dimensionless temperature difference, rotational Brinkman number and the type  of nanofluid on the problem.
