#3 Flow of non-Newtonian fluids

Non-Newtonian fluids are characterized by a viscosity that depends on the rate of deformation of the fluid. They can, for example, be dilatant, as is the case of a mixture of water and cornstarch, or pseudoplastic, such as ketchup. Since many fluids of interest are non-Newtonian, it is crucial that we know their flow properties. In this project, we will use the lattice-Boltzmann method to study the dynamics of non-Newtonian fluids. We want to understand how the flow of the fluid depends on its properties. For example, what is the best angle to empty a glass with swelling fluid as quickly as possible?
