Abstract—In this study, a classical problem stagnation point flow was revisited by using powerfull enough semi numerical analytical technique DQM. A general expression of stagnation point flow is obtained. This equation solved with differential quadrature method (DQM) and Galerkin method. It is seen that obtained results are very closed to each other. But using DQM is more practical and faster than Galerkin. Because polynomial fitting in Galerkin method requires much more time than DQM
Index Terms—component; stagnation point flow, differential quadrature method, galerkin method
