Unsteady squeezing flow of a casson fluid between parallel plates

Squeezing flow of Casson fluid has been taken in to account. Nonlinear ordinary differential equation governing the flow is obtained by imposing similarity transformationon conservation laws. Resulting equation has been solved by using two analytical techniques namely variation of parameters method (VPM) and Adomian’s decomposition method (ADM). Comparison between both the techniques is provided. A numerical solution is also sought to back the analytical results. They are found to be in excellent agreement. Convergence of solution also discussed. Flow behavior under altering involved physical parameters is also discussed and explained in details with graphical aid.
