Far Field Computational Boundary Conditions for Internal Flow Problems

Abstract

Far field computational boundary conditions for 2D internal flow problems are developed from analytic solutions of the linearized Euler equations. The Euler equations are linearized about a constant pressure, rectilinear flow which may have streamwise-normal variations in temperature and velocity as a result of entropy production in the nonlinear computational region. The boundary procedure can be used with any numerical Euler solution method and allows computational boundaries to be placed much closer to the nonlinear region of interest. Keywords: Computational boundary conditions; Internal flow computations; Cascade flow computations.
