Separation Control using Resonant Metamaterials
Abstract
The proposed project will develop theoretical concepts, numerical models, and experimental validation for control of flow separation using resonant metamaterials. The novelty of the proposed research lies in three aspects- (1) use of metamaterials for control of separation, (2) application of the concept to a turbulent flow regime, and (3) physical implementation and experimental verification. Specifically, the project will focus on control of abrupt flow separation over a backward facing step or an open cavity. When the flow separates, unsteady fluctuations of the velocity and pressure adversely affect performance of the air vehicles and military systems. Metamaterials are engineered materials which explore geometric periodicity and an architected design to yield unique and tunable mechanical properties and vibration characteristics. By developing new metamaterial subsurfaces that effectively interact with the fluid flow instabilities, new designs can be achieved that improve the flow characteristics.
