Research Abstract

Turbulent transport characteristics was experimentally investigated in an electrichydrodynamic turbulence in liquid crystal. It was found that it is possible to investigate the effects of rotation on structure formation in turbulence, and that it is also possible to investigate experimentally the spherical symmetric convection in a rotating spherical shell due to replacement of spherical symmetric convection by electrohydrodynamic convection.
