Abstract

Attachment line boundary layer transition on swept cylinders is studied in a low enthalpy hypersonic wind tunnel at M(x) = 7.14. Sweep angles of 60 degrees and 70 degrees are used and transition is detected by means of heat flux measurements. The influence on attachment line transition of single 2D-roughness elements, in the form of tripwires or slots, as well as 3D obstacles is determined and the results are analyzed with respect to Poll's criterion.
