System Validates Soap-Film Study of 2-D Turbulence

Facebook X LinkedIn Email
Studying the flow of soap film has been thought to be a convenient way to study 2-D turbulence in a search for answers to geophysical systems. But research with such models has been inconclusive, largely because methods have enabled only single-point velocity measurements. Researchers at Los Alamos National Laboratory in New Mexico, reporting in Physical Review Letters (Aug. 17, 1998, pp. 1417-1420), have devised a method that measures velocity at thousands of points in a cascade of soap film. The technique measures velocity, vorticity and film thickness simultaneously. Despite some minor...Read full article
