Linear modal and non-modal instability analyses of high-speed laminar separated flow over complex geometries Part II- The HIFiRE-1, ROTEX-T and Oberkampf vehicles
Abstract
Basic research is proposed to address unresolved questions on laminar-turbulent transition mechanisms that condition performance of three vehicles of interest to the Air Force, namely the HIFiRE-1, the ROTEX-T and an Oberkampf body. Canonical problems related to these configurations have been identified and defined as work packages in the proposed research, aiming to advance the understanding of the sequence of linear instability mechanisms that lead high-speed laminar flow on the aforementioned three configurations to transition, from their inception at the bow shock, to their propagation on the conical surface to either a region of Prandtl-Meyer expansion or an axisymmetric laminar separation bubble, and finally to breakdown and turbulence.
