Numerical Study of Boundary Layers With Reverse Wedge Flows Over a Semi-Infinite Flat Plate

摘要

This paper presents the classical approximation scheme to inves-ntigate the velocity profile associated with the Falkner–Skannboundary-layer problem. Solution of the boundary-layer equationnis obtained for a model problem in which the flow field contains ansubstantial region of strongly reversed flow. The problem investi-ngates the flow of a viscous liquid past a semi-infinite flat platenagainst an adverse pressure gradient. Optimized results for thendimensionless velocity profiles of reverse wedge flow are pre-nsented graphically for different values of wedge angle parameternu0001 taken from 0u0002u0001u00022.5. Weighted residual method (WRM) isnused for determining the solution of nonlinear boundary-layernproblem. Finally, for u0001u00030 the results of WRM are compared withnthe results of homotopy perturbation method.
