Nanofluidic energy damper: Modeling, simulation and analysis

Abstract

Nanofluidic energy damper (NED) is recently developed to absorb and damp the mechanical work done by impact load, made by a sealed solid–liquid hybrid system containing solid nanoporous materials and nonwetting liquid. Based upon an entirely new energy damping mechanism, NED shows a great potential not only for giving a high energy damping density but also for performing energy damping behavior repeatedly. Here, we review the recent progress in this field to identify existing issues and opportunities for future studies, including selected numerical and experimental studies related to energy damping mechanism and performance, and some of the key issues associated with the system which might affect the NED’s energy damping density and repeatable energy damping performance.
