In this paper we investigate the rheology of three different classes of edible yield stress
fluids: a) cookie doughs, b) vegetable/fruit purees, and c) protein-rich doughs as used in …

Non-Newtonian fluid mechanics and computational rheology widely exploit elastic dumbbell
models such as Oldroyd-B and FENE-P for a continuum description of viscoelastic fluid …

The finitely extensible nonlinear elastic with Peterlin closure (FENE-P) and simplified Phan-
Thien–Tanner (sPTT) viscoelastic models are used widely for modelling of complex fluids …

Bubble bursting and subsequent collapse of the open cavity at free surfaces of contaminated
liquids can generate aerosol droplets, facilitating pathogen transport. After film rupture …

In this work, we report numerical results on the flow instability and bifurcation of a
viscoelastic fluid in the upstream region of a cylinder in a confined narrow channel. Two …

The FENE-P and sPTT viscoelastic models are widely used for modelling of complex fluids.
Although they are derived from distinct micro-structural theories, these models can become …

Abrupt contraction flows involving viscoelastic fluids represent a longstanding computational
challenge within the field of non-Newtonian fluid mechanics. Despite the apparent simplicity …

We demonstrate that velocity profiles for steady, unidirectional shear flows of the FENE-P
(Finitely-Extensible Nonlinear Elastic, with Peterlin closure) fluid, undergoing canonical …

The stability analysis plays an important role in comprehending the origin of elasto-inertial
turbulence (EIT) of viscoelastic fluid. Currently, there is still a debate on whether it is the …
