Abstract

The objective of the present study is to examine the wall velocity and the Coriolis force effects on the steady magnetohydrodynamic convective flow past a moving semi-infinite vertical flat plate in a rotating fluid, resulting from buoyancy forces which arise from a coupled phenomenon of temperature and species concentration. The similarity equations obtained are solved numerically by a finite difference scheme via the technique of Lobatto III. Velocity, temperature and concentration profiles are presented graphically and the results are discussed and focused on the main effects, ratio the wall velocity and the Coriolis force parameter. The heat and mass transfer rates are entered for various and reasonable values of these specific parameters. All the velocities decrease with the increase of these parameters, whereas the temperature and the concentration profiles increase. An opposite effect is found on Nuxand Shxwhen (Coriolis) and (Ratio) increase.
