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

Experimental study of Taylor’s hypothesis in a turbulent soap film
 Physics of Fluids
, 2000
"... An experimental study of Taylor’s hypothesis in a quasitwodimensional turbulent soap film is presented. A two probe laser Doppler velocimeter enables a nonintrusive simultaneous measurement of the velocity at spatially separated points. The breakdown of Taylor’s hypothesis is quantified using the ..."

Experiments on shallow flow turbulence
 in: Proceedings of the 3rd International Symposium on Environmental Hydraulics
, 2001
"... In shallow flows like rivers and coastal areas, where the depth is small with respect to the horizontal dimensions, the turbulence dynamics is complicated due to the anisotropy in the flow properties. It is therefore hard to predict whether the water depth or a horizontal length scale characterises ..."

EXPERIMENTS ON TURBULENT FLOW SEPARATION
"... A turbulent boundary layer was subjected to adverse pressure gradients of different strengths and the effects this had on the pressure distribution, wall shear stress, mean velocity and perturbation velocity moment profiles were studied. Measurements were made using Particle Image Velocimetry (PIV) ..."

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 wallbounded 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 soapfilm 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 soapfilm
Symmetrypreserving discretization of turbulent flow
 J. Comp. Phys
, 2003
"... We propose to perform turbulent flow simulations in such manner that the difference operators do have the same symmetry properties as the underlying differential operators, i.e., the convective operator is represented by a skewsymmetric coefficient matrix and the diffusive operator is approximated ..."
