| Abstract: | Circular arc,flat plate and sharp cone were used as prototypes to investigate the effects of streamwise curvature and gradient on the stability of compressible boundary layers in the frame work of linear stability theory.The boundary layer profiles on the surface are calculated using the Cebeci Keller box scheme.The stability equations are solved to determine the eigenvalues using a two point fourth order accuracy finite difference scheme.It is shown that convex and concave curvature have different effects on the stability of the flow and the effect of favorable pressure gradient on stability is different for different bodied. |
