| Resumo | |
On airplanes, transition often initiates from small and irregular disturbances introduced into the boundary layer. These disturbances produce TS waves which are modulated both in streamwise and spanwise directions. Such waves are well represented by wavepackets, whose most salient nonlinear feature is the growth of oblique low frequency waves. Experimental results, presented in the literature, additionally indicate the nonlinear growth of fundamental modes. Interestingly, DNS results presented here and in the literature, indicate the nonlinear subharmonic modes are well reproduced numerically but this is not observed for the fundamental modes. Our results also show the subharmonic resonance is substantially less active than previously thought. (AU) | |
