Formation of microfibers and nanofibers by capillary-driven thinning of drying viscoelastic filaments
… et al., Nano Lett., 4(10),2004). We develop a model of this process that describes the simultaneous visco-elasto-capillary thinning, stretching and drying of cylindrical filaments of polymer solutions. A one dimensional formulation is developed using a slender body approximation to the …

Simulation of blood flows in a stenosed and bifurcating artery using finite volume methods and OpenFOAM
… is human blood, a complex fluid which can be modelled via viscoelastic constitutive models. The most commonly used constitutive models for viscoelastic fluids include the OldroydB, Giesekus, Johnson-Segalman, Finitely Extensible Non-Linear Elastic (FENE), Phan-Thein-Tanner (PTT) models etc. …

The Shear and Extensional Rheology of Polymer Dispersions
… regime. Using the experimental data, a numerical model is selected in the rheological classification stage. Numerical models are compared with the experimental data for the best fit with the fluid. The selected numerical model is used for simulation, the final stage, which uses the geometry …
