Abstract
In this study, the magnetohydrodynamics (MHD) boundary layer flow with heat and mass transfer over a vertical infinite plate in a rotating system with periodic suction has been investigated. The system is placed in porous medium and the plate is subjected to heat source or sink. The model problem is solved numerically by the Crank–Nicolson scheme. The numerical results are presented graphically and the conclusion indicates that the flow field and other quantities of physical interest are significantly influenced by flow parameters.
