Artificial boundary conditions for fluid flow simulation

When carrying out numerical simulations of fluid flows in very large or unbounded domains, for example, in physiological fluid mechanics, artificial boundaries have to be introduced in order to define or reduce the size of computational domains and lower the computational cost of the simulations.This motivates several theoretical and numerical studies of Navier-Stokes flows with open boundary conditions. We will address the so-called do-nothing boundary conditions, including the well-posedness of the resulting system of PDEs, as well as numerical experiments that illustrate the effect of such artificial boundary conditions.
