EXPERIMENTS IN TURBULENT SOAP-FILM FLOWS: MARANGONI SHOCKS, FRICTIONAL DRAG, AND ENERGY SPECTRA BY
"... We carry out unprecedented experimental measurements of the frictional drag in turbulent soap-film flows over smooth walls. These flows are effectively two-dimensional, and we are able to create soap-film flows with the two types of turbulent spectrum that are theoretically possible in two dimension ..."

Macroscopic effects of the spectral structure in turbulent flows
- Nature Physics
"... There is a missing link between the macroscopic properties of turbulent flows1–4, such as the frictional drag5 of a wall-bounded flow, and the turbulent spectrum1,6,7. The turbulent spectrum is a power law of exponentα (the ‘spectral exponent’) that gives the characteristic velocity of a turbulent f ..."

fluctuation (or ‘eddy’) of size s as a function of s (ref. 1). Here we seek the missing link by comparing the frictional drag in soap-film flows8, where α = 3 (refs 9,10), and in pipe flows5, where α = 5/3 (refs 11,12). For moderate values of the Reynolds number Re, we find experimentally that in soap-film
on Modeling Draining Flow in Mobile and Immobile Soap Films
, 1999
"... A mathematical model is constructed to describe the two-dimensional flow in a vertical soap film that is draining under gravity. An asymptotic analysis is employed that uses the longwave or “lubrication ” approximation. The modeling results in three coupled partial differential equations that includ ..."

Dynamic Processes in Soap Films
"... ABSTRACT Some relations between the two main types of thin liquid films, the water-in-air "soap " films and the invert oil-in-water "lipid " films, are out-lined, and several dynamic aspects of film behavior are illustrated and briefly reviewed with reference to more complete tre ..."

Experimental study of Taylor’s hypothesis in a turbulent soap film
- Physics of Fluids
, 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 non-intrusive simultaneous measurement of the velocity at spatially separated points. The breakdown of Taylor’s hypothesis is quantified using the ..."
