An investigation of the non-linear instability of flow near a swept attachment-line
Abstract
The present investigation of the nature of the attachment-line boundary layer formed on the windward surface of an infinite swept cylinder, relative to the transition to turbulence, proceeds numerically by using an initial-value approach that departs from the specified spatial- and time-dependence of previous efforts. The full, two-dimensional Navier-Stokes 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 time-periodic 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 z-directions.
