By measuring the optical characteristics of a flow the rheology
of a viscous non-Newtonian fluid - an aqueous solution of hydrolyzed
polyacrylonitrile - has been studied. The loss of stability by the
system with chaotic fluctuations of transparency has been established.
A kinetic model, as well as kinetic equations that describe the flow
of heterogeneous systems, have been suggested. It is expected that
this approach will be used in calculations in oil- and gas production
and filtration of non-Newtonian systems in porous media.
