Abstract:
Investigations of shear flows in three-dimensional complex-plasma fluids
produced in a dc discharge were carried out. The shear was induced
either by an inhomogeneous gas flow or by a laser beam. The viscosity of
complex plasmas was measured over a broad range of shear rates, up to
the hydrodynamic limit when the discreteness becomes important. Analysis
of the measurements reveals non-Newtonian behavior of complex plasmas
accompanied by substantial shear thinning.
