Fluid flow control with transformation media.
Abstract
We introduce a new concept for the manipulation of fluid flow around three-dimensional
bodies. Inspired by transformation optics, the concept is based on a mathematical
idea of coordinate transformations and physically implemented with anisotropic porous
media permeable to the flow of fluids. In two situations-for an impermeable object
placed either in a free-flowing fluid or in a fluid-filled porous medium-we show that
the object can be coated with an inhomogeneous, anisotropic permeable medium, such
as to preserve the flow that would have existed in the absence of the object. The
proposed fluid flow cloak eliminates downstream wake and compensates viscous drag,
hinting at the possibility of novel propulsion techniques.
