Abstract

This paper aims at presenting exact solutions for velocity profile and skin friction coefficient for a fluid in the presence and absence of couple stress. Analytical method is carried out herewith an applied electric field. The results are presented through graphs in each case. Graphs are plotted by giving numerical values to the parameters to depict the effects of velocity and skin friction. It is shown that the velocity increases with the increase in electric number for both with and without couple stress and the skin friction coefficient decreases with increase in electric number in the absence of couple stress parameter.
