In the present study, the influence of slip on entropy generation in magneto- hydrodynamic (MHD) flow over a rotating disk is investigated theoretically. The nonlinear partial differential equations for laminar, steady MHD flow are reduced to a system of multiple coupled nonlinear ordinary differential equations by the Von Kármán approach, which are analytically solved by applying the homotopy analysis method (HAM) with given boundary conditions and verified by numerical quadrature. The convergence of the obtained series solutions is examined in detail. The influence of magnetic interaction number, slip factor and Prandtl number on dimensionless velocity and temperature profiles are presented graphically. Furthermore the effects of magnetic interaction number and slip factor on entropy generation are investigated. The study has applications in optimizing fluid dynamics aspects of novel nuclear thermal MHD space propulsion systems.
