Entropic Lattice Boltzmann Method for Dilute Polymer Solution

Polymer Physics, Department of Materials, ETH Zurich

In the last two decades, Lattice Boltzmann Method emerges as an important tool to simulate hydrodynamics of Newtonian fluids. However, this success story is yet to be repeated in the case of non-Newtonian fluids. In this talk, we will outline how lattice Boltzmann approach for simulation of non-Newtonian fluids can be formulated. In particular, we will demonstrate how analogy between inertial dynamic of FENE dumbbell and Boltzmann Fokker-Planck equation can be used to create fast lattice Boltzmann type solver for FENE dumbbell. Finally, we will discuss how such a polymer solver can be coupled with hydrodynamic solvers.
