%X In this study, we approach a spherical particle in plane Couette fluid flow problem utilizing
Adomian’s decomposition method (ADM) as well as variational iteration method (VIM) to find a
rapidly convergent power series solution. Equation of particle’s motion in Couette flow considering
the rotation and shear effects on lift force and neglecting gravity has been investigated by Vander
Werff. The required time and distance for a spherical particle to reach terminal velocity trajectory
of particle obtained which has application in transferring the medicine in blood in medical area or
control of particles motion during spraying or injecting processes in industry. The precious
contribution of the work is introducing a new fast and efficient solution of analytical methods in a
spherical particle in plane Couette fluid flow over the previous numerical and analytical
counterpart results in literature, while it is shown that both methods give approximations of a high
degree of accuracy and least computational effort for studying particle motion in Couette fluid flow.
