Transonic Flow Calculations for a Wing in a Wind Tunnel [PDF]
Journal of Aircraft, 1981 A computer program has been developed to calculate inviscid transonic flow over a swept wing in a wind tunnel with constant rectangular cross sections and with specified normal or tangential flow at the walls. An approximately orthogonal computational grid that conforms to the wing and the tunnel walls was developed for application of the Jameson ...

Aerodynamic Free-Flight Conditions in Wind Tunnel Modelling through Reduced-Order Wall Inserts
Fluids, 2021 Parallel sidewalls are the standard bounding walls in wind tunnels when making a wind tunnel model for free-flight condition. The consequence of confinement in wind tunnel tests, known as wall-interference, is one of the main sources of uncertainty in ...
