Abstract
The microbial polysaccharide xanthan was studied theologically as well as in its behaviour in the flow through a packed bed of spheres. Corr ecting for shear, the remaining non-viscous increase in resistance sta rts at stress levels which in viscometric flows elastic effects (first normal stress differences) start to dominate viscous ones (shear stre ss).
