Abstract

Present study deals with the magnetohydrodynamic flow of nanofluid in a rotating disk with variable thickness in the presence of injection / suction parameter. In this paper, water is considered as a base fluid and silver as a nanoparticle. Primarily, Generalized Von Karman transformations are applied to attain the ordinary differential equations from the nonlinear partial differential equations. By employing HAM technique, the characteristics of flow and heat transfer are computed. Heat and Mass transfer subject to volume fraction of silver nanoparticles in the presence of injection / suction are investigated. Homogeneous and Heterogeneous reactions are taken into account. Impact of pertinent parameters such as disk thickness index, dimensionless constant, Reynolds number, Grashof number, magnetic parameter, Prandtl number on velocity, temperature and concentration are investigated. It is observed that with an increase in disk thickness the radial, axial and azimuthal velocities are enhanced. Magnitude of concentration increases for larger Schmidt number.
