Abstract

The global methods of generalized differential quadrature GDQ andgeneralized integral quadrature GIQ are applied to solve threedimensional,incompressible, laminar boundary layer equations. The streamwise andcrosswise velocity components are taken as the dependent variables. Thenormal velocity is obtained by integrating the continuity equation along thenormal direction where the integral is approximated by GIQ approach with highorder of accuracy. All the spatial derivatives are discretized by a GDQscheme. After spatial discretization, the resultant ordinary differentialequations are solved by the 4stage RungeKatta scheme. Application ofGDQGIQ approach to a test problem demonstrated that accurate numericalresults can be obtained using just a few grid points.
