Query: Eelectrokinetic turbulence and chaos in ionic migration and in
  microfluidic convection   Turbulence in the ionic migration and in the microfluidic
electro-hydrodynamic convection (mixing) under constant and low-frequency
external electric field has been studied using distributed chaos approach and
notion of effective (turbulent) diffusivity. Results of corresponding
laboratory experiments have been also used for this purpose. It is shown that
for the migration and convection (mixing) under constant and low-frequency
external electric field the turbulent power spectra have stretched exponential
form $E(k) \propto \exp-(k/k_{\beta})^{2/3}$. In the case of the microfluidic
convection the distributed chaos is tuned to the large-scale coherent
structures generated by the low-frequency oscillating external electric field (
$k_{\beta}$ is proportional to the forcing frequency).
