Two-dimensional turbulence: a review of some recent experiments
WebThe rupture of soap films is traditionally described by a law accounting for a balance between momentum and surface tension forces, derived independently by Taylor and … WebIridescent colors of soap bubbles or films arise due to interference between light reflected from two surfactant-laden surfaces that are ~ 100 nm - 10 micron apart. Sandwiched between these interfacial layers is a fluid that drains primarily under the influence of gravitational and capillary or interfacial forces, including disjoining pressure. Below 50 … Web6 de mar. de 2000 · An experimental study of Taylor’s hypothesis in a quasi-two-dimensional turbulent soap film is presented. A two-probe laser Doppler velocimeter enables a nonintrusive simultaneous measurement of the velocity at spatially separated points.
