computer extended series and ham for the solution of nonlinear squeezing flow of casson fluid between parallel plates

The paper presents analysis of twodimensional nonnewtonian incompressible viscous flow between parallel plates. the governing problem of momentum equations are reduced to node using similarity transformations. the resulting equation is solved using series solution and homotopy analysis method. these methods have advantages over pure numerical methods for obtaining the derived quantities accurately for various values of parameters and results are valid in much larger parameter domain compared with numerical schemes.
