Wakes

Fluid flow wakes are the hydrodynamic signatures left by a moving body or carried by a fluid passing a body at some relative velocity. In dictionaries it is defined as “a trail of disturbed water or air left by the passage of a ship or aircraft”. Of course there are many other meanings of this word, but we focus here on only the fluid flows. More specifically our lab deals with turbulent wakes.
