About

Jack J. McNamara is a professor in the Department of Mechanical & Aerospace Engineering at The Ohio State University. His research interests are broadly in the areas of fluid-structural interactions and model reduction of high-dimensional dynamical systems, with an interconnected goal of improving basic understanding and computational methods. A core application target is air vehicle operation in high-speed flow regimes, where there is a potential for complex interactions at both the component (fluid-thermal-structural-material) and vehicle (aero-servo-thermo-elastic-propulsive) levels. Other application areas include fluid-structural centric problems associated with ship airwakes, wind turbines, flapping wing air vehicles, automobiles, and turbomachinery. He is the director of the Multi-Physics Interactions Research Group (MIRG) at The Ohio State University.

• Hypersonic Oscillating Shock-Wave/Boundary-Layer Interaction on a Flat Plate

  AIAA Journal · 2021 · 27 citations

  This work discusses the design, measurement, and simulation of an oscillating shock-wave/boundary-layer interaction on a flat plate at Mach 5.8 and . The shock generator is free to pitch and oscillates with a frequency of 42 Hz, resulting in a shock that varies in intensity and impingement point, with a maximum flow-deflection angle of approximately 10 deg. Transition appears to take place downstream of the separated region for both static (with a fixed flow-deflection angle) and dynamic experim…

• Numerical Investigation of a Turbulent High-Speed Flow Separating from a Deforming Cantilever Plate

  AIAA Journal · 2023-02-01 · 11 citations

  article

  Deep understanding of multiscale nonlinear phenomena, such as shocks, turbulent flow, and separation, is critical for the accurate and efficient treatment of high-speed fluid–structural interactions. To better characterize the principal issues, a numerical investigation is performed of the response of a Mach 2.0 flow to prescribed motion of a cantilever plate. The main features of the flow are separation at the end of the plate and re-attachment on the downstream floor, which are modulated by sh…

• One-Way Fluid-Structure Interactions in Turbulent Shock-Boundary Layer Interactions

  2024-01-04 · 10 citations

  article

  Fluid-Structure Interactions (FSI), especially associated with shock-boundary layer interactions (SBLI), play a significant role in the design and performance of high-speed vehicles. Two-way FSI simulations involving SBLI, while needed for comprehensive understanding, are prohibitively expensive for parametric studies. One-way studies not only offer a way to assess FSI sensitivities and identify the parameter space for targeted fully-coupled campaigns but also allows us certain insights into flu…
