Abstract

The steady MHD thin film flow of a Johnson-Segalman fluid on a vertical surface is modeled as well as analyzed numerically. Two problems regarding lifting and drainage are investigated. The effect of different parameters such as Stokes number S_t, Weissenberg number W_e, the ratio of viscosities φ, slip parameter α, and applied magnetic fiel M² emerging in the model on velocity fields for the both case are studied graphically.
