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…

A Quantitative Study of Energy Localization Characteristics in Defect-embedded Phononic Crystals
Vinod Ramakrishnan, Kathryn H. Matlack
Phononic crystals (PnCs) are periodic engineered media that can customize the spatio-temporal characteristics of mechanical energy propagation. PnCs that additionally leverage prec…
