Stability analysis of boundary-layer transition using accurate velocity profiles obtained by an advanced LES
Laminar-turbulent transition of the boundary layer is discussed from a view point of ac- curacy of the computational uid dynamics. When highly accurate velocity profiles are used for stability analysis, curve of N factor of the e N method becomes apart from the curve of conventional laminar- ow computation. Furthermore, N value does not reach sufficient large value even in the situation that laminar-turbulent transition may occur. With the excellent computation, usefulness of the accurate velocity profiles for the transition issue is sought.
