The Role of Far-Field Boundary Conditions in Numerical Solutions of the Navier-Stokes Equations.

Abstract

The problem of prescribing farfield boundary conditions on the outer computational domain boundary is discussed. Several boundary conditions which have been used in the literature are compared with two newly proposed sets. The proposed boundary conditions are shown to be non-reflecting and superior in both accuracy and time to convergence. Graphs showing the numerical results for the different types of boundary conditions are displayed and the wave motion demonstrated. (Author)
