Abstract:
Many fluids of industrial or biological interest such as blood, paint...
are non-Newtonian, which means that their flows cannot be described by the
Navier-Stokes equations. In order to simulate such a flows, it is possible
to use so-called mesoscopic models. Mathematically, these models can be
written in two equivalent forms: either as stochastic differential equations
or as deterministic Fokker-Planck (FP) equations. The talk will introduce
numerical methods which have been designed to solve efficiently those
equations. Numerical results will show the superiority of the deterministic
approach (solving the FP equation) over the stochastic approach.
