Dispersion rheology at microgravity: what can it teach us?

Rheol. is one of the few methods which can be used for analyzing coagulation behavior in concd. dispersions. This is important for handling both theor. and practical problems. For understanding the rheol. behavior of concd. dispersions, expts. performed under microgravity conditions are useful. [on SciFinder (R)

The Peclet number for shear thinning in hard sphere dispersions

An alternative definition is introduced for the Peclet no., Pe, related to the shear thinning of dispersions. Its significance is demonstrated by using it in the interpretation of published exptl. data. The values of the Pe for the transition from the Brownian to the hydrodynamic regime in hard-spheres dispersions are presented graphically. [on SciFinder (R)
