چکیده:
The effect of a fluid’s elasticity has been investigated on the vortex break down phenomenon in confined swirling flow. Assuming that the fluid obeys upper-convected Maxwell model as its constitutive equation, the finite volume method together with a collocated mesh Was used to calculate the velocity profiles and streamline pattern inside a typical lid-driven swirling flow at different Reynolds and Weissenberg numbers. The flow Was to be steady and axisymmetric. Based on the results obtained in this work, it can be concluded that fluid’s elasticity has a strong effect on the vortex break down completely reversing its direction of rotation depending on the Weissenberg number. Also, the effect of suction and injection on the flow structure of both Newtonian and viscoelastic fluids Was surveyed. Based on our results, uniform suction and injection tend to diminish Newtonian and elastic vortices.
