Characteristics of electroconvection turbulence and proposal of its application to turbulent transport experiment in a rotating spherical shell
Abstract
An electroconvection (EC) in liquid crystal is used in the experimental study of turbulent transport. The transport characteristics in EC turbulence were investigated with a planer cell, and the diffusive property of turbulent transport was identified, which is identical to that of normal viscus fluid described by Navier-Stokes equation. Experimental research on turbulent transport using EC in a rotating spherical shell is proposed. A demonstration of the production of EC turbulence in a rotating spherical shell was carried out, where the radial gravity was replaced by electric field.
