Simulations of shear banding in paints

W.J. Briels, A. van den Noort
University of Twente, The Netherlands

A coarse grain model to simulate the rheological properties of paints will be presented. The model shows extreme shear thinning at shear rates as low as several reciprocal seconds. In several cases shear banding was found along the gradient direction. Not only were shear rates different in different bands, but also their densities. Special attention will be paid to the evolution of the stress during the period when the systems settles from its initial homogeneous state to the final banded state. © IWNET 2006
