Numerical boundary conditions for flow problems
Abstract
The development, analysis, and implementation of numerical boundary conditions for flow calculations in infinite domains are discussed. Emphasis is placed on potential flow, periodic acoustic, and incompressible viscous flow problems. In all cases, the infinite domain problems are approximated by problems posed on a bounded domain. To close the numerical problem, an artificial numerical boundary condition is imposed. The effect of these approximate boundary conditions on the accuracy of the numerical computations is examined.
