Numerical study of boundary layers with reverse wedge flows over a semi-infinite flat plate

This paper presents the classical approximation scheme to investigate the velocity profile associated with the Falkner--Skan boundary-layer problem. Solution of the boundary-layer equation is obtained for a model problem in which the flow field contains a substantial region of strongly reversed flow. The problem investigates the flow of a viscous liquid past a semi-infinite flat plate against an adverse pressure gradient. Optimized results for the dimensionless velocity profiles of reverse wedge flow are presented graphically for different values of wedge angle parameter [beta] taken from 0 [less than or equal to] [beta] [less than or equal to] 2.5. Weighted residual method (WRM) is used for determining the solution of nonlinear boundary-layer problem. Finally, for [beta] = 0 the results of WRM are compared with the results of homotopy perturbation method. [DOI: 10.1115/1.3173763]
