nn-PINNs: Non-Newtonian physics-informed neural networks for complex fluid modeling.
Soft Matter, 2021 Time- and rate-dependent material functions in non-Newtonian fluids in response to different deformation fields pose a challenge in integrating different constitutive models into conventional computational fluid dynamic platforms.

Propulsion in a viscoelastic fluid
, 2007 Flagella beating in complex fluids are significantly influenced by viscoelastic stresses. Relevant examples include the ciliary transport of respiratory airway mucus and the motion of spermatozoa in the mucus-filled female reproductive tract. We consider

Rheology of waxy oils: A critical review
Applications in Engineering ScienceWaxy oil is a rheologically complex material presenting shear-rate-dependent viscosity, static and dynamic yield stresses, gel elasto-viscoplasticity, time/deformation-dependent gel structure, and irreversibility.

Mathematical Analysis of Casson Fluid Model for Blood Rheology in Stenosed Narrow Arteries
Journal of Applied Mathematics, 2013 The flow of blood through a narrow artery with bell-shaped stenosis is investigated, treating blood as Casson fluid. Present results are compared with the results of the Herschel-Bulkley fluid model obtained by Misra and Shit (2006) for the same geometry.

Drop Formation in Non-Newtonian Fluids [PDF]
Physical Review Letters, 2013 We study the pinch-off dynamics of droplets of yield stress and shear thinning fluids. To separate the two non-Newtonian effects, we use a yield stress material for which the yield stress can be tuned without changing the shear thinning behavior, and a shear thinning system (without a yield stress) for which the shear thinning can be controlled over a ...
