Abstract:In this paper, direct numerical simulations in hypersonic turbulent boundary layers over a
$24^{\circ }$
compression ramp at Mach 6.0 are performed. The wall skin friction and its spanwise non-homogeneity in the interaction region are analysed via the spectral analysis and drag decomposition method. On the compression ramp, the premultiplied spanwise energy spectrum of wall shear stress
$\tau _{w}$
reveals two energetic spanwise length scales. One occurs … Show more
