The objective of this effort was the development of improved methods for obtaining accurate boundary conditions for CFD simulation of transonic wind tunnel flows. An experimental study of the cross-flow characteristics of five perforated transonic wall geometries is reported. A correlation, collapsing the cross-flow characteristics of all five geometries is obtained. Cross-flow is found to be dependent on local wall pressure and boundary layer displacement thickness. A relation between cross-flow velocity and equivalent inviscid normal velocity (flow angel) is derived. A set of equations is given allowing the simultaneous numerical solution for cross-flow velocity, boundary layer displacement thickness, and equivalent inviscid normal velocity - given the pressure distribution and test section inlet displacement thickness.
