Transparent Boundary Conditions for Aeroelastic Problems in Wind
Tunnels
Transparent conditions on open boundaries of a wind tunnel for
time-dependent transonic flow problems are proposed. Under
assumption that the far field is described by the Euler equations
linearized about the free-stream flow, we obtain exact conditions
on inflow and outflow cross-sections of a computational domain. The
exact conditions are non-local; therefore a special attention is
paid to the efficient numerical implementation of our formulae.
Examples of numerical calculations are discussed.
