Beyond first-order accuracy in continuous-forcing immersed boundary methods, and their well-conditioned projection-based solution
Diederik Beckers, H. Jane Bae, Andres Goza
We introduce a refined immersed boundary (IB) methodology that is better-than-first-order accurate in practice, while preserving key properties of "continuous-forcing" IB approache…
Weakly coupled fluid-structure interaction between wall-bounded turbulent flows and defect-embedded phononic subsurfaces
Ching-Te Lin, Vinod Ramakrishnan, Andres Goza +2
We investigate the interaction between wall-bounded turbulence and defect-embedded phononic subsurface (D-Psub) using a weakly coupled fluid--structure framework, in which the flow…
A Framework to Systematically Study the Nonlinear Fluid-Structure Interaction of Phononic Materials with Aerodynamic Flows
Vinod Ramakrishnan, Arturo Machado Burgos, Sangwon Park +2
Phononic materials (PMs) are periodic media that exhibit novel elastodynamic responses. While PMs have made progress in vibration-mitigation applications, recent studies have demon…
Dynamic interactions between an aerodynamic flow and a flexible flat plate
Srikumar Balasubramanian, Andres Goza
Passive flow control via fluid-structure interaction (FSI) is a promising paradigm for unmanned aerial vehicles operating in vortex-dominated low Reynolds number regimes. A flexibl…
