Abstract: In a previous paper (Pantokratoras and Magyari, 2009), the Electro-Magnetohydro dynamic (EMHD) free convection flow of a weakly conducting fluid from an electromagnetic actuator was considered. In the present note, we study the cases where the Riga-plate either moves with constant velocity (Sakiadis flow) or the Riga-plate is situated in a constant free stream (Blasius flow). The results are obtained with the numerical simulation of the governing equations. Velocity profiles are presented, as well as values of the skin friction. Results are presented for both impermeable and permeable Riga-plate with uniform suction or uniform injection.

Keywords: Blasius flow; Sakiadis flow; Riga plate; boundary layer; electromagnetohydrodynamics; EMHD flow; free convection flow; weakly conducting fluids; electromagnetic actuators; constant velocity; constant free stream; numerical simulation; modelling; skin friction; uniform suction; uniform injection.
