<dd>Highly accurate far field computational boundary conditions for inviscid, two-dimensional isentropic duct flow problems are developed from analytic solutions of the linearized, second-order Euler equations. The Euler equations are linearized about a constant pressure, rectilinear flow condition. The boundary procedure can be used with any numerical Euler solution method and allows computational boundaries to be located extremely close to the nonlinear region of interest. Numerical results are presented which show that the boundary conditions and far field analytic solutions provide a smooth transition across a computational boundary to the true far field conditions at infinity. The cost of upgrading first-order boundary conditions to second-order is slight</dd>
