From their images of viscoelastic jets, the researchers also measured the rate at which each ligament thinned, also known as the liquid's relaxation time.
for time t ∈ R + and arc-length parameter s ∈ ( 0, L ( t ) ) with jet length L. The balance, constitutive and coupling equations describe the dynamics and behavior of a viscoelastic jet with cross-section A, momentum-associated velocity v, pressure p, stress component σ and jet curve γ.
The mechanical behavior of viscoelastic materials combines elements of both viscous fluid and elastic solid responses.
In the past years, the asymptotic behavior of viscoelastic equations with past history has been studied by many authors (see [22 27]).
Realistic configurations of the external electric field between the electrodes were employed, as well as the linear and non-linear, Upper-Convected Maxwell, models were used to describe the viscoelastic behavior of the polymer jets.
Topic of this work are viscoelastic jets.
They are located in front of the jets to control flow field and mixing behavior of the jets.

Several viscoelastic models such as Boltzmann, Burgers, and power-law models are considered to characterize the time-dependent behavior of linear viscoelastic materials.
What we found is not in line with the behavior of traditional viscoelastic models.
