Abstract: We use a two-dimensional Lattice Boltzmann method for a non-linear Jeffreys model to simulate a rising bubble in a non-linear viscoelastic medium and show that the experimentally observed cusp at the end of the bubble is reproduced in our simulations.

Keywords: Lattice Boltzmann method; Lattice Boltzmann model; binary fluid flow; drops; viscoelastic flow; convected Jeffreys model; rising bubble; simulation; polymeric materials.
