Abstract:

The Navier Stokes equations are solved, numerically, to determine the symmetric laminar incompressible flow past blunted wedges. Similarity-type variables are used in a coordinate system that comprises the optimal coordinates for the corresponding boundary-layer problem. This formulation leads to better numerical accuracy and produces the correct solution near the leading edge, far downstream and transversely far from the wedge surface. The flow over parabolas, the flat plate, and the vertical wall are obtained as particular cases of the present solutions and compare well with the available results for these problems. The numerical method is an implicit alternating direction method that converges rapidly to accurate results. Author
