Summary: We propose lattice Boltzmann implementations of several Navier-Stokes outflow boundary conditions like the zero normal-stress, the Neumann, and the do-nothing rule. A consistency analysis using asymptotic methods is given and the algorithms are numerically tested in two space dimensions with respect to accuracy and interaction with the inner flow field.
