Numerical and theoretical stability studies are conducted for a supersonic M = 2.0 flow over a flat plate with a spanwise strip of distributed suction. Propagation of artificially excited 3D wave trains relevant to the first-mode instability are considered. Direct numerical simulations (DNS) as well as assessments based on the linear stability theory (LST) are performed using the in-house code “HSFlow++” (High Speed Flow solver). It is shown that, despite strong spatial nonuniformities of the mean flow near the suction strip ends, the e-N method based on the local-parallel LST gives reasonable estimates of the laminar flow control performance of the suction strip.
