Viscoelastic Phase Separation in Shear Flow
, 2004 We numerically investigate viscoelastic phase separation in polymer solutions under shear using a time-dependent Ginzburg-Landau model. The gross variables in our model are the polymer volume fraction and a conformation tensor.

Effect of magnetic field on thermal instability of a rotating Rivlin-Ericksen viscoelastic fluid
International Journal of Mathematics and Mathematical Sciences, 2006 The thermal instability of a rotating Rivlin-Ericksen viscoelastic fluid in the presence of uniform vertical magnetic field is considered. For the case of stationary convection, Rivlin-Ericksen viscoelastic fluid behaves like a Newtonian fluid.

The bounce-splash of a viscoelastic drop
, 2008 This is an entry for the Gallery of Fluid Motion of the 61st Annual Meeting of the APS-DFD (fluid dynamics videos). This video shows the collision and rebound of viscoelastic drops against a solid wall. Using a high speed camera, the process of approach,

Lattice Boltzmann method for viscoelastic fluids
Physical Review E, 2002 Lattice Boltzmann model for viscoelastic flow simulation is proposed; elastic effects are taken into account in the framework of Maxwell model. The following three examples are studied using the proposed approach: a transverse velocity autocorrelation function for free evolving system with random initial velocities, a boundary-driven propagating shear ...

On effect of viscoelastic characteristics of polymers on performance of micropump
Advances in Mechanical Engineering, 2017 Micropumps are the most important components of lab-on-a-chip devices, which are becoming popular recently due to their enormous advantages. Among the different designs of micropumps, the nozzle–diffuser valveless design is the most preferred one due to ...

Durotaxis in viscoelastic fluids
Physical Review FluidsOrganisms often swim through fluids that are spatially inhomogeneous. If the fluids are polymeric, gradients in polymer concentration may lead to gradients in both fluid viscosity and elasticity. In this letter, we present theoretical results for the dynamics of active particles, biological or otherwise, swimming through spatially inhomogeneous ...
