Inlet and Outlet Open Boundary Conditions for Incompressible Navier-Stokes Equations

Abstract:
Flow simulation models often contain open boundaries in order to avoid computations on too large or infinite domains. The open boundary conditions partially drives the ow and the inuence of the outer domain has to be taken into account on such boundaries. "Free" open boundary conditions are then essential to the model. The goal of this work is to introduce a new open boundary condition, adapted both for inlet and outlet, parametrized and driven by simple informations such as ow rate.
Keywords:
Navier-Stokes equations, open boundary conditions
