N2 - A numerical study of the interaction between an impinging oblique shock-wave and a laminar boundary-layer on a flat plate is carried out to investigate the resulting twodimensional separation bubble at a freestream Mach number of 2.0 for the approach flow. The flow parameters used for the present investigation matches the laboratory conditions in the experiments conducted by Hakkinen et al.1 The skin friction and pressure distribution from the simulation are compared to the experimental and numerical results available in the literature. The results also confirm the asymmetric nature of the separation bubble reported in the literature. In addition, the development of low-amplitude disturbances is investigated to study the linear stability of the laminar separation bubble. Furthermore, the effects of increased shock incidence angle and Reynolds number are also investigated.
