Turbulence in Aqueous Glucose Solutions Induced by Magnetic Field

Section: Soft Matter
Original Author's Text: Ukrainian

Abstract: The turbulent motion induced by a magnetic field in aqueous glucose solutions has been studied. Changes in the motion occurring owing to variations in the magnetic field induction and the solution concentration are analyzed. The dependence of the turbulent motion synchronization degree on the magnetic induction is found to be nonmonotonic. The minimum in this dependence is found to be connected with the emergence of unstable fluctuation modes. The following growth of the synchronization degree is explained by a strengthening of the hydrodynamic interaction between anisotropic clusters. Higher solution concentrations are found to reduce the synchronization degree. This fact is a consequence of the mutual compensation of perturbations created by different clusters.

Key words: aqueous glucose solution, magnetic field, turbulence, synchronization degree.
