On the role of initial velocities in pair dispersion in a microfluidic chaotic flow
Eldad Afik, Victor Steinberg
Chaotic flows drive mixing and efficient transport in fluids, as well as the associated beautiful complex patterns familiar to us from our every day life experience. Generating suc…
Elastic turbulence in a curvilinear channel flow
Yonggun Jun, Victor Steinberg
We report detailed quantitative studies of elastic turbulence in a curvilinear channel flow in a dilute polymer solution of high molecular weight polyacrylamide in a high viscosity…
Statistics of tumbling of a single polymer molecule in shear flow
Sergiy Gerashchenko, Victor Steinberg
We present experimental results on statistics of polymer orientation angles relatively to shear plane and tumbling times in shear flow with thermal noise. Strong deviation of proba…
Single polymer dynamics: coil-stretch transition in a random flow
S. Gerashchenko, C. Chevallard, V. Steinberg
By quantitative studies of statistics of polymer stretching in a random flow and of a flow field we demonstrate that the stretching of polymer molecules in a 3D random flow occurs…
Chaotic flow and efficient mixing in a micro-channel with a polymer solution
Teodor Burghelea, Enrico Segre, Israel Bar-Joseph +2
Microscopic flows are almost universally linear, laminar and stationary because Reynolds number, , is usually very small. That impedes mixing in micro-fluidic devices, which so…
Elastic turbulence in curvilinear flows of polymer solutions
Alexander Groisman, Victor Steinberg
Following our first report (A. Groisman and V. Steinberg, $\sl Nature$ , 53 (2000)) we present an extended account of experimental observations of elasticity induced turbu…
