Numerous works analysis has showed that the viscous fluid during flow in microcapillary cracks, in specific range of cracks sizes, behaves as non-Newtonian system [2, 3, 9 and others].
However, there is no consensus on the mechanism of the anomalous behavior manifestation of Newtonian fluids and rheological properties strengthening of the non-Newtonian systems in the microcapillary cracks.
An Non-Newtonian system
does not follow Newtonian law (viscosity = Shear stress / shear rate).

In contrast to the Newtonian case, there are relatively few publications on droplet behavior in non-Newtonian systems
Fluid Mechanics chapters include basics on non-Newtonian systems
which, for instance find importance in polymer and food processing, flow through piping, flow measurement, pumps, mixing technology and fluidization and two phase flow.
What makes this book even more special is, in my opinion, its tacit yet strong message that particle non-Newtonian systems
are still an exciting and very challenging field of research where many important problems remain unresolved or subject of controversy.
PS particles crosslinked with DVB, when mixed in a PMMA matrix, however, produce highly non-Newtonian systems
VisiMix 2000 LAMINAR, the latest addition to the VisiMix family, can model mixing in highly viscous Newtonian and non-Newtonian systems
, such as polymerization reactors, slurries and pastes.
