• Nonlinear transition mechanism on a blunt cone at Mach 6: oblique breakdown

  Journal of Fluid Mechanics · 2021 · 44 citations

  Abstract

• Numerical Investigation of Nonlinear Boundary-Layer Transition for Cones at Mach 6

  AIAA Journal · 2021 · 13 citations

  Direct numerical simulations were carried out for a straight and a flared cone at Mach 6 and zero angle of attack to investigate the effects of geometry on the linear and nonlinear stages of the laminar–turbulent transition process. The cone geometries and the flow conditions of the simulations are chosen to closely match those of the experiments conducted at the Boeing/AFOSR Mach 6 Quiet Tunnel (BAM6QT) at Purdue University. In the linear (primary) instability regime the flared cone resulted in…

• Direct Numerical Simulations of Hypersonic Boundary-Layer Transition for a slender cone

  AIAA Aviation 2019 Forum · 2020 · 7 citations

  1st authorCorresponding

  Direct Numerical Simulations (DNS) were carried out to investigate the laminar-turbulent transition process for a slender (2.5◦ half-angle) straight (right) cone at Mach 6 at zero angle of attack. The slender cone geometry of the experiments in the Boeing/AFOSR Mach 6 Quiet Tunnel (BAM6QT) at Purdue University was used for the numerical investigations. The simulation results indicate that the so-called fundamental breakdown was the dominant nonlinear mechanism in the downstream part of the slend…

• Fin-induced Shock Boundary Layer Interactions on a Flat Plate and Hollow Cylinder at Mach 5

  AIAA SCITECH 2022 Forum · 2022 · 6 citations

  View Video Presentation: https://doi.org/10.2514/6.2022-1816.vid An experimental investigation of Shock Boundary Layer Interaction (SBLI) topologies around unswept fins in Mach 5 flow has been conducted with a range of Reynolds numbers, boundary layer states, and fin-base shapes. Geometries are based on the DLR STORT flight test program, featuring a θ=20deg deflection and r=h=0.015 leading edge bluntness. The fin is mounted on a cylindrical base geometry with radius r=h=1.37. A laminar flat-plat…

• Development of Plasma-based Controlled Disturbances for the Study of Boundary Layer Transition and Shock Boundary Layer Interaction

  AIAA Aviation 2019 Forum · 2021 · 4 citations

  View Video Presentation: https://doi.org/10.2514/6.2021-2822.vid Plasma actuators have been developed and studied for the use of controlling hypersonic boundary layer physics. The goal is to manipulate the incoming boundary layer state to control the behavior of shock boundary layer interactions (SBLIs). The surface based plasma actuators, referred to as localized arc filament plasma actuators (LAFPAs), deposit energy into the flow and excite otherwise less amplified boundary layer instabilities…
