What is it about?
High-speed aerodynamics is characterized by specific phenomena among which shock-boundary layer interactions (SBLI) play a dominant role. This kind of interactions frequently occurs in various practical flow configurations such as supersonic air intakes, ejection nozzles of rocket engines or supercritical wings of modern transonic aircraft. Since shock-boundary layer interaction is detrimental to the aerodynamic performance and structural integrity of these systems, it must be mitigated. This study investigates the effect of microramps on SBLI and assesses their potential for reducing the undesirable effects of these interactions.

Why is it important?
The unsteady mechanisms that characterize SBLI are a limiting factor for the design of supersonic/hypersonic aircraft systems. The study of control devices capable of reducing the negative impact of SBLI is therefore necessary and constitutes an important step in the process of optimizing these systems. From this perspective, microramps are robust and easy-to-implement devices that can noticeably improve the situation. From a research point of view, an in-depth understanding of the physical mechanisms at play when a microamp wake impinges on canonical SBLI is a fundamental milestone in isolating the important parameters that influence the control efficiency of these devices.
