Abstract
A numerical simulation of the flow of a non-Newtonian viscoelastic fluid around a sphere was carried out using a Maxwell type constitutive equation and a mixture of an optimization process and an expansion process. The influence of elasticity and inertia on the detailed flow structure are studied for a small wall effect.
In the range of Weissenberg and Reynolds numbers studied, there was little variation in the streamline distribution, but large qualitative shifts in the maximum shear rate and stress patterns. The results are compared with experimental data.
