Chaos analysis of viscoelastic chaotic flows of polymeric fluids in a micro-channel
AIP Advances, 2015 Many fluids, including biological fluids such as mucus and blood, are viscoelastic. Through the introduction of chaotic flows in a micro-channel and the construction of maps of characteristic chaos parameters, differences in viscoelastic properties of ...

Shear thinning of a critical viscoelastic fluid [PDF]
Physical Review E, 2005 The frequency and shear dependent critical viscosity at a correlation length $ξ=κ^{-1}$, has the form $η=η_{0}κ^{-x_η}G(z_{1},z_{2})$, where $z_{1}$ and $z_{2}$ are the independent dimensionless numbers in the problem defined as $z_{1}=\frac{-iω}{2Γ_{0}κ^{3}}$ and $z_{2}=\frac{-iω}{2Γ_{0}κ_{c}^{3}}$.

A microstructure model for viscoelastic–thixotropic fluids [PDF]
, 2020 A microstructure model to describe the viscoelasticity and thixotropy properties of complex fluids is proposed. The model is based on the Lodge–Yamamoto network theory and is an extension of the Phan-Thien–Tanner model, with a kinetic process in which ...

Abstract and Applied Analysis, 2013 Fluids subject to thermal gradients produce complex behaviors that arise from the competition with gravitational effects. Although such sort of systems have been widely studied in the literature for simple (Newtonian) fluids, the behavior of viscoelastic

Orientational dynamics and rheology of active suspensions in weakly viscoelastic flows
Communications Physics, 2023 Microswimmer suspensions in Newtonian fluids exhibit unusual macroscale properties, such as a superfluidic behavior, which can be harnessed to perform work at microscopic scales.

AIP Advances, 2017 Elastic instabilities could happen in viscoelastic flows as the Weissenberg number is enlarged, and this phenomenon makes the numerical simulation of viscoelastic fluids more difficult.

Autophoretic locomotion in weakly viscoelastic fluids at finite Péclet number [PDF]
, 2017 In this work, we numerically investigate the dynamics of a self-propelling autophoretic Janus particle in a weakly viscoelastic fluid. The self-propulsion is achieved by an asymmetry in the properties of the surface of the Janus particle that drives a ...

Bubble growth in a two-dimensional viscoelastic foam [PDF]
, 2006 The effects of viscoelasticity on the expansion of gas bubbles arranged in a hexagonal array in a polymeric fluid are investigated. The expansion is driven by the diffusion of a soluble gas from the liquid phase, and the rate of expansion is controlled ...

, 2011 In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.
