DNS of Mack-Mode Damping on Porous Coated Cones

Lüdeke, Heinrich and Viola, Wartemann (2011) DNS of Mack-Mode Damping on Porous Coated Cones. 4th European Conference for Aerospace Sciences, 2011-07-04 - 2011-07-08, St. Petersburg, Russland.

Full text not available from this repository.


The flow field over a 3° blunt cone is investigated with respect to a hypersonic stability analysis of the boundary-layer flow at Mach 6 with and without porous walls by comparing local DNS and LST data. The original boundary-layer profile is generated by a finite volume solver, using shock capturing techniques to generate an axisymmetric flow field. Local boundary-layer profiles are extracted from this flow field and hypersonic Mack-modes are superimposed for cone-walls with- and without a porous surface, used as a passive transition-reduction device. Special care is taken on curvature effects of the wall on the mode development over smooth and porous walls.
