Optical Fiber Measures Turbulence

Kathleen G. Tatterson

A team of physicists from the University of Pittsburgh and the University of Bordeaux, France, has demonstrated a fiber optic device that measures the two-dimensional turbulence of fluids quickly and inexpensively. This development could simplify the study of fluid mechanics, medicine and manufacturing processes. Vorticity is a property of fluids in which the liquid swirls around a central point like a whirlpool. In a study published in Physical Review Letters, researchers described how the optical fiber velocimeter measured the vorticity fluctuations in a turbulent soap film flow,...Read full article
