Fluid-flow control by metamaterials

We are developing a strategy for manipulating fluid flows in pipes and mitigating flow-induced vibrations. We use compact metamaterials with extremely low-frequency working ranges, which are placed externally on pipes, and combine them with bio-inspired sensors for precise flow characterization.

High-speed flows and variations in the pipe geometry create turbulence that causes unwanted vibrations and raises exploitation costs. Therefore, control over flow turbulence is of high practical demand. Efficient solutions for long-span pipes are still lacking because of very low frequencies (a few Hz) of excited vibrations .

MetaFlow proposes a pioneering approach to stabilize flows by emerging metamaterials that can locally control flow energy through carefully tuned solid-fluid interactions.
