Exact solutions for the flow of a generalized second grade due to a Longitudinal quadratic time-dependent shear stress

EXACT SOLUTIONS FOR FLOW OF A SISKO FLUID IN PIPE

By means of He's homotopy perturbation method (HPM) an approximate solution of velocity eld is derived for the ow in straight pipes of non-Newtonian uid obeying the Sisko model. The nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to He. Furthermore, the obtained solutions for velocity eld is graphically sketched...

Some exact solutions for the helical flow of a generalized Oldroyd-B fluid in a circular cylinder

Unsteady Falkner-skan Flow of a Second Grade Fluid

The non-similar solutions for the unsteady flow of a second grade fluid wereconstructed. The method of perturbation was used for the solution of the governing non-linear equation. The results of Rajagopal et al. (Int. J. Non-Linear Mechanics, 1983) can be obtained as a special case of the presented analysis.
