Abstract

A phononic material and a method of using a phononic material for use in interacting with a fluid or solid flow are provided. In one implementation, a phononic material includes an interface surface and a subsurface feature. The interface surface moves in response to pressure and/or velocity gradients associated with complex motion of a turbulent flow. The subsurface feature extends from the interface surface and comprises a phononic crystal or locally resonant metamaterial adapted to receive the pressure and/or velocity gradients from the turbulent flow via the interface surface and alter the phase and amplitude of a plurality of frequency components of the turbulent flow to reduce or increase the kinetic energy of the turbulent flow. The interface surface is adapted to vibrate at a plurality of frequencies, phases and amplitudes in response to the frequency, phase and amplitude of at least one component of the turbulent flow.
