Quantifying the effect of resonant amplitude and frequency of phononic material vibrations on the coupled fluid-structure interaction dynamics in separated aerodynamic flows
Vinod Ramakrishnan, Arturo M. Burgos, Sangwon Park +2
Phononic materials (PMs) with engineered resonances have been leveraged for fluid-structure interaction (FSI) with fluid flow instabilities, yielding beneficial outcomes such as tr…
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…
Intrinsic phase based proper orthogonal decomposition (IPhaB POD): a method for physically interpretable modes in near-periodic systems
Akhileshwar Borra, Zoey Flynn, Andres Goza +1
Fluid dynamics systems driven by dominant, nearly periodic large-scale dynamics are common across wakes, jets, rotating machinery, and high-speed flows. Traditional decomposition t…
Adjoint-based optimal actuation for separated flow past an airfoil
Ernold Thompson, Andres Goza
This study computes the optimal normal actuation on the surface of a NACA0012 airfoil at an angle of attack of 15° and a Reynolds number of Re = 1000, using costs defined for minim…
