This paper deals with the various methods of making the flows of fluids (i.e. liquids and gases) applications, and the information that be gained from a visible flow field. Fluid flows become visible in one of two ways: introduction of a foreign substance into the medium (e.g. smoke in air) or measuring optical properties that change while the fluid is flowing (e.g. the optical index of refraction of a gas is a function of its density). Photographs are included which illustrate both methods and their applications, for example for reducing aerodynamic drag in automobile designs.
