A novel shear flow instability triggered by a chemical reaction in the absence of inertia
T. Burghelea, K. Wielage-Burchard, I. A. Frigaard +2
We present an experimental investigation of a novel low Reynolds number shear flow instability triggered by a chemical reaction. An acid-base reaction taking place at the interface…
Elastic turbulence in von Karman swirling flow between two disks
Teodor Burghelea, Enrico Segre, Victor Steinberg
We discuss the role of elastic stress in the statistical properties of elastic turbulence, realized by the flow of a polymer solution between two disks. The dynamics of the elastic…
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…
Mixing by polymers: experimental test of decay regime of mixing
T. Burghelea, E. Segre, V. Steinberg
By using high molecular weight fluorescent passive tracers with different diffusion coefficients and by changing the fluid velocity we study dependence of a characteristic mixing l…
