The stability of steady shear flows of some viscoelastic fluids relative to small perturbations in the initial data is examined. It is shown that at all values of the steady shear rate where the flow curve exhibits a zero or negative slope the flow is unstable. This conclusion is corroborated by exi
LDA experiments have been conducted in a twodimensional steady streaming flow field in order to determine the secondary velocity profiles. We describe here an LDA system developed to resolve small secondary-flow velocities and to detect flow reversals due to viscoelasticity. Results compare well wit
