OF THE RHEOMETRIC FLOW OF A VISCOELASTIC FLUID

UDC 519.6:532.62

The flow between two plates in the phase of establishment 
for the case of a viscoelastic fluid in comparison with a Newtonian 
fluid is investigated numerically and analytically. The quantitative 
and qualitative features of the flow are analyzed. It is noted that 
in a number of cases this flow has wave features, and it is determined 
that the presence of viscoelasticity usually increases the time of 
establishment of the flow. It is pointed out that some of the revealed 
features of the flow can be used in experimental investigations of 
non-Newtonian fluids.
