Weissenberg effect

[′vīs·ən‚bərg i‚fekt]
(fluid mechanics)
An alteration of the normal stresses in a non-Newtonian fluid on account of elasticity, so that such a fluid, when placed between two concentric, rotating cylinders, can rise on the inner cylinder in spite of centrifugal forces.

287 g, Weissenberg effect became aggravated due to high molecular weight at the final stage.
The Weissenberg effect was due to higher consistency more pronounced for 2.
This axial force is what gives rise to the Weissenberg effect described earlier.
In addition, the material transport along the rotor shafts due to the Weissenberg effect increases the load of the dust stops.
Furthermore, the material transport caused by the Weissenberg effect can be reduced.
When the temperature is lower than 40[degrees]C, the steady shear measurement could not be performed because of Weissenberg effect (rod-climbing), which is one of the most important phenomena exhibited by certain viscoelastic fluids (41), (42).
The monomer concentrations of acrylamide and other vinyl monomers were limited at low level because of Weissenberg effect and stabilization demand [13].
