Abstract:

The remnants of ellipticity in the parabolized stability equations for three dimensional parallel incompressible boundary layer flow are studied, detail methods for removing the ellipticity are suggested, and the consistence of solutions between the parabolized stability equations and the fully elliptic problem is provoed.

Key words: th ree-dimensional incomp ressible boundary layer, parabo lized stability equat ions, ellip t icity
