An investigation of the nonlinear instability of flow near a swept attachmentline
Abstract
The present investigation of the nature of the attachmentline boundary layer formed on the windward surface of an infinite swept cylinder, relative to the transition to turbulence, proceeds numerically by using an initialvalue approach that departs from the specified spatial and timedependence of previous efforts. The full, twodimensional NavierStokes equations are solved under the conventional assumptions as to the form of the stagnation point and of the Hiemenz flows. Attention is given to the timeperiodic form for the low quantities. The accuracy of all solution methods is noted to critically depend on the choice of the appropriate grids in the y and zdirections.
