Abstract
Laminar flow control by suction of crossflow-dominated laminar-turbulent transition at Mach 2 was studied experimentally and numerically as part of the EU project SUPERTRAC. The measurements were performed in the Ludwieg Tube Facility (RWG) at DLR Göttingen. With a suction panel manufactured from porous sinter material a significant delay of laminar-turbulent transition could be achieved. Transition N-factors in the range of 5 to 7.5 were obtained for both the reference model and the model with suction system. Thus, a reduction of the transition Nfactor due to increased roughness and the non-uniform suction distribution on the suction panel was not noted. Moreover, the experimental and numerical results indicated that transition was dominated by travelling crossflow instabilities.
