Abstract
The behavior of the Johnson-Segalman fluid in a Couette geometry is investigated with a combination of numerical, anal. and simulation techniques. The results strongly suggest that there exists a selection mechanism for the position of the interface of discontinuity due to the constitutive instability typical of models with non-monotonic constitutive equations. This implies that the spurt phenomenon exhibits a jump discontinuity instead of a change of slope in the flow curve. [on SciFinder(R)]
