Entropy generation analysis for non-similar analytical study of nanofluid flow and heat transfer under the influence of aligned magnetic field

The present semi-analytical investigation covers the impact of aligned magnetic field, Ohmic dissipation and viscous dissipation on a non-similar nanofluid flow over a plate with no flux condition. The system of equations is transformed into the non-dimensional system of nonlinear partial differential equations to get solution using homotopy analysis method (HAM). The entropy generation analysis measuring disorderness of the system is also presented. The influence of physical parameters on momentum, temperature and concentration boundary layer thickness is discussed. The secondary variables (C-f; Nu) and entropy generation number (Ns) are also explored for present MHD model. The angle of inclination of magnetic field is found be controlling parameter for the minimization of skin friction. (C) 2018 Faculty of Engineering, Alexandria University.
