Abstract
The steady free surface motion of a layered medium of viscoelastic fluids driven by a vertical rotating rod and the free surface motion of a viscoelastic fluid between vertical, eccentric, rotating cylinders is solved by means of domain perturbations. The flow field, the shape of the free surfaces and the interface and the climb at the rod are determined by expanding the stress in a series of Rivlin-Ericksen tensors and developing the theory as a perturbation of the rest state in powers of the angular frequencyΩ of the rod or of the cylinders. It is shown that rheometrical measurements in the rotating rod geometry are reliably reproducible whilst concentric cylinder geometry presents important practical problems in measuring rheological constants.
