Witryna12 sty 2010 · The viscosity coefficient values are characteristic for individual phases and the values of η decrease as a function of increasing shear rate (ν) and temperature. A drop in the value of η with an increase in shear rate, characteristic of non-Newtonian fluids, and transition to a Newtonian fluid at a given temperature were found. WitrynaA Newtonian fluid is a fluid in which the viscous stresses arising from its flow are at every point linearly correlated to the local strain rate — the rate of change of its deformation over time. Stresses are proportional …
