Controlling Elastic Turbulence
Reinier van Buel, Holger Stark
We demonstrate through numerical solutions of the Oldroyd-B model in a two-dimensional Taylor-Couette geometry that the onset of elastic turbulence in a viscoelastic fluid can be c…

Dissipative systems with nonlocal delayed feedback control
Josua Grawitter, Reinier van Buel, Christian Schaaf +1
We present a linear model, which mimics the response of a spatially extended dissipative medium to a distant perturbation, and investigate its dynamics under delayed feedback contr…

Elastic turbulence in two-dimensional Taylor-Couette flows
R. van Buel, C. Schaaf, H. Stark
We report the onset of elastic turbulence in a two-dimensional Taylor-Couette geometry using numerical solutions of the Oldroyd-B model, also performed at high Weissenberg numbers…
