Numerical simulation of drop deformation in shear
We consider a drop of one liquid suspended in another liquid, which is sheared, as a model of a Couette device. Numerical simulations are conducted with an in-house volume-of-fluid (VOF) code, with either a continuous surface force (CSF) algorithm with piecewise linear interface reconstruction, or with a more accurate but computationally more intensive paraboloid representation of the interface (PROST). The methodology will be presented. The Oldroyd-B and Giesekus constitutive models are implemented. Comparison with recent experimental results of P. Moldenaers (KU-Leuven) will be discussed.
